"Rafal Mazur's involvement with music began in his youth with violoncello studies in Krakow. He switched to bass guitar in the late 1980's. Since 2000 he has played an acoustic bass guitar built to his own specifications by luthier Jerzy Wysocki. He has developed an advanced and individual approach to his instrument, and to improvisation in general, in which sonority, extended technique and gesture combine effortlessly in performance. He has taken an important role in Kraków to support young artists and improvised music. A founder of the ImproArt studio of improvisation, he has performed jazz and improvised music in clubs and festivals across Poland and Europe, and in China, South Korea and Israel. In recent years he has collaborated with Lisa Ullen, Frederic Blondy, Charlotta Hug, Raymond Strid, Keir Neuringer, Zsolt Sores and others. His current focus is the band "Ensemble 56" and "Mazur/Neuringer Duo". He is an organizer of the Laboratory of Intuition, a series of spontaneous art presentations in Kraków. Mazur's main field of interest and activity is collective and solo free/spontaneous improvisation. In his practice as an improvising musician and on his way to mastery/artistry he studys Chinese philosophy (Jagiellonian University). He regards Taoism as a strong base for the enrichment of the improviser's attitude, and to this end he practices the Taoist's martial art TaiJi Quan Chen. For Mazur, following the masters of Chinese philosophy and martial arts is crucial in the development of a state of mind prepared for the unexpected situations an improviser encounters in the act of collective free improvisation. During the Polish Sound Art in China tour in 2006, Mazur presented lectures in NiHiLo Gallery in Foshan and Zendai Art Museum in Shanghai, taking the opportunity to meet Chinese improvisers and discuss and compare his approaches to improvisation, Taoism and TaiJi. Mazur's most recent work is the first album of solo acoustic bass guitar free improvisation: 'Sonor Forms'. Released by independent label DTS Records in Krakow on its Transidiomatic series, the disc is the result of investigation into the practice of solo free improvisation."

"Born in Buenos Aires, Argentina, in 1941, American composer and clarinet player Guillermo Gregorio has lived variously in Europe and the United States since 1986. Leading his Chicago-based trio and other ensembles, Gregorio has performed extensively, and his compositions have been recorded on numerous CDs by the Swiss label hatART and the American labels New World Records, Atavistic, and Nuscope, among others. His works have been played by noted New Music ensembles in the USA and Europe, among them Makrokosmos Ensemble (Switzerland) , Ensemble N_ER (EU), International Contemporary Ensemble (USA), Fonema Consort (USA), and the Maverick Ensemble (USA). In addition, as an instrumentalist, Gregorio has worked with many experimental and improvisational groups, including those that recorded the music of Cornelius Cardew, Anthony Braxton, and Philip Corner, among other contemporary composers (see discography for details).

As a composer and improviser, Gregorio has collaborated with Fred Lonberg-Holm, Ran Blake, Steffen Schleiermacher, Steve Swell, Jim O'Rourke, Ken Vandermark, Mats Gustaffson, Axel Dörner, Josh Abrams, Jeff Parker, Jason Adasiewicz, Carrie Biolo, George Graewe, Franz Koglmann, Thomas Lehn, Heiner Reinhardt, Le Quan Ninh, Akikazu Nakamura, Ab Baars, Sebi Tramontana, Mary Oliver, Klaus Koch, Gene Coleman, Enrique Gerardi, Paulo Alvares, Vinko Globokar, Makrokosmos Quartet, François Houl, and Stephen Dembski, among others.

He participated in the Argentine experimental music scene throughout the 1960s, '70s, and early '80s. His involvement with New Music included both composing and playing clarinet, saxophone and miscellaneous instruments in the Movimiento Música Más (Fluxus Group), the Experimental Group of Buenos Aires, and the Group of Contemporary Music of La Plata, featuring Fluxus events, multi-media spectacles, environmental pieces, and experimental concerts. Some of his earlier work in Argentina is available in the CD Guillermo Gregorio: Otra Música. Tape Music, Fluxus and Free Improvisation in Buenos Aires 1963-70 (Atavistic UMS/ALP209CD). After leaving Buenos Aires Gregorio had the opportunity to experience the European creative music scene of the middle '80s, i.e. the fruitful convergence of Free Jazz and 20th-century music and its interconnections with visual art. The interaction with composers and artists of that milieu constituted an indelible mark in his further explorations.

Gregorio-a visual artist himself-has frequently explored the intersection of visual and musical experience. His involvement in visual arts and design is a central influence in his music. In his series entitled "Madi Pieces" and "Coplanars" (1999-2005) Gregorio used Constructivist and geometrically generated ideas in scores ranging from conventionally notated material to graphic systems and open structures. In these compositions, a reinterpretation of the fundamental and structural concepts of Constructivism converges with the historical experiences of Argentinean Conceptualism, Fluxus, intermedia synthesis, and graphic realization. In January 2001, he founded the Madi Ensemble of Chicago, which performed original and historical scores that draw from the conceptual foundation of diverse Argentinean avant-garde currents. His scores related to that period have been exhibited in numerous shows at galleries and institutions, among them the Block Museum of Art (Northwestern University, Evanston, IL), Chelsea Museum of Art (NY), Kettle's Yard Gallery (University of Cambridge, UK), and Elastic, Sound & Vision Gallery (Chicago). Some of Gregorio's works belong to the permanent collections of the MADI Museum and Gallery in Dallas, Texas, and the Centre d'Art Geometrique MADI in Paris. His works have been published in Leonardo, Journal of the International Society for the Arts, Sciences and Technology, Notations 21 (Mark Batty Publisher), Noon Literary Annual, and other specialized publications. His series of pieces entitled "Otra Música" (2005 to the present), composed using conventional notation, focus on history and critical issues as well as syntactic aspects of texts and music. Still maintaining the openness of the works from the former period, the name of the series-"Otra Música"-refers to the title of a monthly column on experimental and avant-garde sounds that Gregorio wrote for a specialized magazine in Buenos Aires during the early '70s. Currently, Gregorio's interests are related to improvisation and "composition in real time" playing clarinet, in addition to the aforementioned compositions.

Gregorio has a degree in Architecture, and has worked as a graphic designer. As an educator he taught history and theory of architecture at the University of Buenos Aires, Argentina, and history of industrial design and visual communication at the University of La Plata, Argentina. In the USA he has taught history of 20th-century art and art appreciation at Purdue University North Central, Indiana, sound improvisation at the School of the Art Institute, Chicago, and worked as advisor of Grad Projects in the Sound Department of that School. At the present time Gregorio teaches History of Communication Design at Columbia College, Chicago."

"Artur Majewski is a trumpeter, born in Wrocław in 1978. Known as a member of Robotobibok, Mikrokolektyw and the Foton Quartet, as well as for his improvisations with various artists.

He started his musical career at a young age on piano but at the age of 10 he switched to the trumpet. In 2002 he graduated from Music Academy in Katowice under world famous trumpeter Professor Piotr Wojtasik . Majewski's thesis focused on the output of Don Cherry - a godfather of avant-garde-jazz trumpet. Robotobibok

During his studies he co-founded Robotobibok (a portmanteau of the Polish words for robot and slacker), a band which explored the boundaries of rock, jazz, electronic and drum'n'bass. Its popularity in late 1990s and early 2000s was considerable in Poland as well as in other European countries. In 2002 they toured the United States and Europe, visiting London, Paris, Brussels, Amsterdam, Vienna, Berlin, and Zagreb. During the nine years of Robotobibok's existence they released three albums: Jogging (2000), Instytut Las (Institute Forest, 2003) and Nawyki Przyrody (Nature's Habits 2004). An independent recording company - OM Vytvornia - founded by Robotobibok's members, published all of them.

Mikrokolektyw

Together with Robotobibok's drummer Kuba Suchar, Artur Majewski founded a duet - Mikrokolektyw (Microcollective). It is regarded as one of the most important combos in Polish improvised music. Its value can be proved by enthusiastic reviews and the fact that they are the only Polish band that publishes its albums in the world-famous recording label Delmark Records run by Ken Vandermark.

Other collaborations

Majewski is also a member of Foton Quartet, alongside Gererd Lebik, Wojtek Romanowski and Kuba Cywiński. So far, they have released one album, Zomo Hall, published by celebrated NOT Two Records. He cooperates with the Szczecin band Kristen, as well, and tours in a duet with bass player Rafał Mazur. With him, Anna Kaluza and Kuba Suchar, he recorded the album entitled Tone Hunting, which was published by Portuguese improvised music label Clean Feed Records.

Years into his career, thanks to his unprecedented artistic abilities and his own original musical language, Artur Majewski has become one of the most interesting improvisers in Europe and has started to draw more and more attention from American improvisers. He cooperates regularly with Rob Mazurek in his famous Exploding Star Orchestra and with Joshua Abrahms and his Chicago-based Natural Information Society."

"Born on October 9, 1958 in Tokyo, Japan, Fujii began playing piano at four and received classical training until twenty, when she turned to jazz. From 1985-87, she studied at Boston's Berklee College of Music, where her teachers included Herb Pomeroy and Bill Pierce. She returned to Japan for six years before returning to the US to study at the New England Conservatory in Boston, where her teachers included George Russell, Cecil McBee, and Paul Bley, who appeared on her debut CD Something About Water (Libra, 1996).

Since then Fujii has been an innovative bandleader and soloist, a tireless seeker of new sounds, and a prolific recording artist in ensembles ranging from duos to big bands. She has showcased her astonishing range and ability approximately 80 CDs as leader or co-leader. With each new recording or new band, she explores new aspects of her art.

Regular collaborations include her New York trio with bassist Mark Dresser and drummer Jim Black, augmented by trumpeter/husband Natsuki Tamura to form the Satoki Fujii Four; her duo with Tamura; the Satoko Fujii Quartet featuring Tatsuya Yoshida of the Japanese avant-rock duo, The Ruins; Orchestra New York, which boasts the cream of New York's contemporary avant garde improvisers, including saxophonists Ellery Eskelin and Tony Malaby, trumpeters Herb Roberton and Steven Bernstein, and trombonist Curtis Hasselbring, among others; Orchestra Tokyo, drawing on that city's best improvisers; Orchestra Nagoya; Orchestra Kobe; the co-operative trio Junk Box with Tamura and percussionist John Hollenbeck; ma-do, a quartet including Tamura on trumpet, bassist Norikatsu Koreyasu, and Akira Horikoshi; the Min-Yoh Ensemble with Tamura, trombonist Hasselbring, and accordionist Andrea Parkins; the Satoko Fujii New Trio, featuring bassist Todd Nicholson and drummer Takashi Itani― plus countless engagements and collaborations with some of the world's most important improvisers."

"Japanese trumpeter and composer Natsuki Tamura is internationally recognized for a unique musical vocabulary that blends extended techniques with jazz lyricism. This unpredictable virtuoso's seemingly limitless creativity led François Couture in All Music Guide to declare that "... we can officially say there are two Natsuki Tamuras: The one playing angular jazz-rock or ferocious free improv... and the one writing simple melodies of stunning beauty... How the two of them live in the same body and breathe through the same trumpet might remain a mystery."

Born on July 26, 1951, in Otsu, Shiga, Japan, Tamura first picked up the trumpet while performing in his junior high brass band. He began his professional music career after he graduated from high school, playing in numerous bands including the World Sharps Orchestra, Consolation, Skyliners Orchestra, New Herd Orchestra, Music Magic Orchestra, and the Satoko Fujii Ensemble, as well as in his own ensemble. He was the trumpeter for numerous national television shows in Japan from 1973-1982, including The Best Ten, Music Fair, Kirameku Rhythm and many others.

In 1986, he came to the United States to study at Berklee College of Music. He then returned to his native Japan to perform and teach at the Yamaha Popular Music School and at private trumpet studios in Tokyo and Saitama, before coming back to the US to study at New England Conservatory. He made his debut recording as a leader in 1992 on Tobifudo.

In 1997 he released the duo album How Many? with pianist Satoko Fujii, who is also his wife. It marked the beginning of an artistic collaboration that continues up to the present. The duo has made a total of five CDs over the years, including 2012's Muku. "Muku contains some truly stunning, spine-tingling music...its sheer beauty and elegance is what lingers most," wrote Dave Wayne in All About Jazz. "Fujii's orchestral technique, clear chromatic lines and "prepared piano" devices contrast effectively with Tamura's arsenal of extended techniques which he executes with a warm, vocalized tone throughout the trumpet's full range," Ted Panken said in his four-star DownBeat review. Tamura's collaborations with Fujii reveal an intense musical empathy, and have garnered wide popular and critical acclaim. Jim Santella in All About Jazz described their synergy well in his glowing review of the couple's 2006 Not Two disc, In Krakow, In November: "... the creative couple forcefully demonstrates what can happen when you let your musical ideas run free... Similarly, Tamura's mournful trumpet can fly high or low in search of his next surprise. Oftentimes, they both issue plaintive moans that sing like angels on high." Their sixth duet album is due out in 2017.

In 1998, Tamura began recording his unaccompanied solo performances. The stunning solo trumpet debut release, A Song for Jyaki earned a Writers Choice 1998 in Coda magazine, and Andy Bartlett wrote in Coda, "A fabulous set of hiccuping leaps, drones and post-bop trumpet hi-jinx. Tamura goes from growling lows to fluid, free solo runs and echoes not only Don Cherry's slurring anti-virtuosic chops but also Kenny Wheeler's piercing highwire fullness." He followed it up in 2003 with KoKoKoKe, which Jon Davis described in Exposé as "Buddhist chants from an alien planet." Grego Applegate Edwards explains that on Tamura's most recent solo album, 2013's Dragon Nat, "he pares down to focus on simple unwinding melodic material, the sound of his trumpet as a sensuous thing, a periodicity. Taken as a whole it is a kind of environmental tone poem for the moment Natsuki is in now."

2003 was a breakout year for Tamura as a bandleader, with the release of Hada Hada, featuring his free jazz-avant rock quartet with Fujii on synthesizer. Peter Marsh of the BBC had this to say about the high voltage CD: "Imagine Don Cherry woke up one morning, found he'd joined an avant goth-rock band and was booked to score an Italian horror movie. It might be an unlikely scenario, but it goes some way to describing this magnificent sprawl of a record." The quartet's 2004 Quartet release Exit was deemed "...a brilliantly executed set with a neon glow," by Dan McClenaghan in All About Jazz.

In 2005, Tamura made a 180-degree turn in his music with the debut of his all acoustic Gato Libre quartet. Focusing on the intersection of European folk music and sound abstraction, the quartet featured Fujii on accordion, Kazuhiko Tsumura on guitar, and Norikatsu Koreyasu on bass. The quartet's poetic, quietly surreal performances have been praised for their "surprisingly soft and lyrical beauty that at times borders on flat-out impressionism," by Rick Anderson in CD Hotlist. Dan McClenaghan in All About Jazz described their fourth CD, Shiro, as "intimate, something true to the simple beauty of the folk tradition...Tamura's career has largely been about dissolving musical boundaries. With Gato Libre and Shiro, the trumpeter extends his reach even deeper into the prettiest, most accessible of his endeavors." After the unexpected passing of Norikatsu in 2012, Tamura added trombonist Yasuko Kaneko to the group. The new configuration has toured Europe and Japan and released its debut recording, DuDu, in 2014. "DuDu follows the winning formula of its predecessors but, as with the other discs, eschews the formulaic. The result is another sublimely satisfying, elegant record that brims with raw excitement and a reflective nostalgia," writes Hrayr Attarian in All About Jazz. With the tragic death of guitarist Kazuhiko Tsumura, Gato Libre is now a trio. They will release a CD and LP in 2017.

In 2010, Tamura debuted a new electric quartet, First Meeting, featuring Fujii, drummer Tatsuhisa Yamamoto and electric guitarist Kelly Churko. Their first release, Cut the Rope, is "is a noisy, free, impatient album, and ranks among Fujii and Tamura's most accomplished," according to Steve Greenlee in the Boston Globe.

While fronting groups and recording as a leader, Tamura has also played an integral role in nearly all of Satoko Fujii's many projects. He is featured on all of the CDs by Satoko Fujii's various orchestras (NY, Tokyo, Nagoya, Kobe, and Berlin) and has contributed original compositions and arrangements to each of their 19 critically celebrated albums. In addition, he was a featured soloist in the Satoko Fujii Quartet, her avant-rock free jazz group that also included Tatsuya Yoshida of The Ruins. Of his work on the quartet's 2003 release Minerva, Mark Keresman wrote in JazzReview.com, "Natsuki Tamura's trumpet has some of the stark, melancholy lyricism of Miles, the bristling rage of late 60s Freddie Hubbard and a dollop of the extended techniques of Wadada Leo Smith and Lester Bowie."

Tamura is a vital member of Fujii's Min-Yo Ensemble as well. "Tamura tempers his avant-garde antics with an innate lyricism," wrote Steve Smith of Time Out New York in his review of Fujin Raijin, the intimate acoustic quartet's debut CD. He's also been singled out for his contributions to Fujii's ma do ensemble. "With Tamura's brash and glowing lines, the band incorporates mesmeric ostinatos and thrusting opuses into the grand schema," Glenn Astarita wrote in Ejazznews about their first CD, Desert Ship.

Collaborative groups also play an important role in Tamura's career. Most recently, Tamura joined Fujii and two French musicians, trumpeter Christian Pruvost and drummer Peter Orins, to form Kaze, which made their recording debut in 2011. In 2015, they released their third album, Uminari, which Jazz Magazine (France) called, "a compelling example of free jazz today. Compositions are perfectly scripted, with a well-oiled interaction and playing of beautiful power..." The collaborative trio Junk Box, which he co-founded in 2006 along with pianist Fujii and drummer John Hollenbeck, plays Fujii's "composed improvisations," graphic scores that take "ensemble dynamics to great creative heights," says Kevin Le Gendre in Jazzwise. Their music "is full of bluster and agitation that nonetheless retains moments of great melodic beauty, usually by way of concise, pertly pretty motifs that trumpeter Tamura plays in between bursts of withering roars that often dissolve into austere overtones." Their premiere CD, Fragment, appeared in 2006. As Daniel Spicer wrote of Fragment in JazzWise, "Tamura spits out gloriously rude Lester-Bowie-like snorts, lows like a herd of robotic cattle or makes like a wheezy howler monkey... Cool and clever." Glenn Astarita of All About Jazz declared it "Required listening."

Along the way, there have been one-off cooperative groups and sideman appearances for Tamura as well. In the Tank, an ad hoc quartet with Fujii and electric guitarists Takayuki Kato and Elliott Sharp, is a "triumphant electro-acoustic adventure" according to Daniel Spicer of Jazzwise. "Think AMM meets blues guitar meets 1970s Miles Davis and you get some idea of the disc's flavor: a slow-moving panorama for the ears, where sounds are systematically added, repeated, refined, and replaced in turn," wrote Nate Dorward in Cadence. Tamura and Fujii were one of two piano/trumpet duos featured on the Double Duo Crossword Puzzle CD, a live recording with Dutch trumpeter Angelo Verploegen and pianist Misha Mengelberg. Tamura has also toured and recorded with saxophonist Larry Ochs' Sax and Drumming Core, and appeared on albums by drummer Jimmy Weinstein, saxophonist Raymond McDonald, and CDs by Japanese free-jazz pioneers trumpeter Itaru Oki and pianist Masahiko Sato. In 2014 he released Nax, a duet album with bassist Alexander Frangenheim. Tamua has toured throughout Japan, North America, and Europe, appearing at major jazz festivals, concert halls, and clubs."

"Ramon Lopez was born on August 6th 1961 in Alicante, Spain. Drummer, Percussionist and Composer. He began as a self-taught drummer in the mid-1970's. Witnessing a Max Roach solo concert in 1980 was a turning point that fundamentally changed his understanding of music. He was part of local groups until he decided to move to Paris in January 1985 and became increasingly involved in the experimental scene in France. At the same time, he developed an interest in Indian music, and took tabla lessons with Krishna Govinda K.C. He is currently a student of Pandit Subhankar Banerjee, while teaching Indian music himself with Patrick Moutal at the Paris Conservatory (1994-2001) His first recording as a leader, an album of solo drums, was released in 1997 on the British Leo label linked to free jazz music and improvisation. Besides Jazz and Indian music, he is attracted especially to flamenco music. He has worked with some of the great flamenco artists, among them Carmen Linares, Esperanza Fernández, Inés Bacán, Gerardo Núñez, Rafael de Utrera, Chano Domínguez, etc... His musical endeavours have always been challenging; his interpretation of songs from the Spanish civil war (2001) spring to mind, or his duos dedicated to Roland Kirk (2002). From 1997 to 2000 he was drummer in the renowned French Orchestre National de Jazz under Didier Levallet, who continues to expand the traditional vocabulary of the orchestra with new elements. Among many others, Lopez has worked at concerts and festivals and in the recording studio with the following musicians of the jazz avant-garde: Beñat Achiary, Rashied Ali, Majid Bekkas, Anthony Coleman, Andrew Cyrille, Sophia Domancich, Agustí Fernández, Glenn Ferris, Sonny Fortune, Barry Guy, Charles Gayle, Teppo Hauta-Aho, Howard Johnson, Hans Koch, Joachim Kuhn, Daunik Lazro, Jeanne Lee, Thierry Madiot, Roscoe Mitchell, Joe Morris, Ivo Perelman, Enrico Rava, Paul Rogers, Louis Sclavis, Alain Silva, Archie Shepp, John Surman, Claude Tchamitchian, Mal Waldron, Christine Wodrascka... Ramon Lopez is an un-typical percussionist. He is a musician who has mastered a number of different musical traditions. He loves to work with artists from other disciplines, with actors, choreographers or visual artists. He is currently one of the most respected European musicians in the area of contemporary jazz or improvised music. The French government named him "Chevalier of the Order of Arts and Letters" in 2008."-Jorge García, Institut Valencia de la Musica.
