"Roy Sinclair Campbell Jr. (September 29, 1952 - January 9, 2014) was an American trumpeter frequently linked to free jazz, although he also performed rhythm and blues and funk during his career.

Born in Los Angeles, California, in 1952, Campbell was raised in New York City. At the age of fifteen he began learning to play trumpet and soon studied at the Jazz Mobile program along with Kenny Dorham, Lee Morgan and Joe Newman. Throughout the 1960s, still unacquainted with the avant-garde movement, Campbell performed in the big bands of the Manhattan Community College. From the 1970s onwards he performed primarily within the context of free jazz, spending some of this period studying with Yusef Lateef.

In the early 1990s Campbell moved to the Netherlands and performed regularly with Klaas Hekman and Don Cherry. In addition to leading his own groups, he performed with Yo La Tengo, William Parker, Peter Brotzmann, Matthew Shipp, and other improvisors. Upon returning to the United States he began leading his group Other Dimensions In Music and also formed the Pyramid Trio, a pianoless trio formed with William Parker. He performed regularly as part of the Festival of New Trumpet Music, which is held annually in New York City.

He died in January 2014 of hypertensive atherosclerotic cardiovascular disease at the age of 61."

"John Dikeman was born in Nebraska in 1983 and grew up in Kemmerer, Wyoming. Thanks to the extreme isolation of his hometown, he spent most of his free time practicing and studying music. He quickly discovered the music of John Coltrane, Cecil Taylor, John Zorn, and Albert Ayler and instantly connected to the unmatched expressive power of free jazz. John was very fortunate to meet and collaborate with many excellent improvisers at a rather early age. Dikeman started performing professionally at the age of 16 after meeting New Mexican guitarist Stefan Dill who became a mentor for John. Stefan also introduced Dikeman to Jack Wright who was living in Boulder, Colorado at the time. Jack would prove to be one of John's biggest influences and a long time collaborator (as well as short term landlord). John also spent a summer in Arkansas where he was able to woodshed and perform with saxophonist Keefe Jackson and bassist Jon Barrios.

Dikeman left Wyoming in 1999 to study saxophone and composition at the Interlochen Arts Academy and then briefly at Bennington College where he attended courses with drumming legend Milford Graves and was also able to collaborate regularly with drummer Ben Hall. John also studied privately with Joe Maneri during this period.

John then moved to New York City for one year where he worked as a satellite dish technician while performing as much as possible. After NYC, John moved to Philadelphia. Frequent collaborators of this time included Daniel Carter, Lukas Ligeti, and Ty Cumbie in The Color Now Band, Nate Wooley, Mike Pride, Jonathan Vincent, Jack Wright, Toshi Makihara, Jon Barrios, Kurt Heyl, Zack Fuller, Reuben Radding, Ava Mendoza, Raed Yassin, Daniel Carter, Jonathan Fretheim, Mike Barker and many others.

In 2004, Dikeman moved to Cairo, Egypt. In the three years he was there, he worked regularly as a performer, studio musician, and teacher. He performed as a soloist with the Cairo Symphony Orchestra, played and traveled throughout North Africa with Nubian pop star Mohamed Mounir, led his own jazz bands which performed weekly in downtown Cairo, performed and recorded with DJ Haze, played countless weddings and party's with The Riff Band, and served as the saxophonist in most Egyptian bands that needed one. He also performed at the Lebanese improvised music festival, Irtijal, in 2005 and 2006.

John moved to Amsterdam in December of 2007, after a brief stay in Budapest, Hungary. Since arriving in Amsterdam, John has jumped at the chance to re-enter the world of improvised music. John performs regularly in the Netherlands in venues including the Bimhuis, Paard van Troje, Café Wilhelmina, Paradox, Lindenberg, OT301, etc... John is also a curator for the OT301 New Music and Dance Program as well as the Tabula Rasa series at the Maarten Luther Kerk. Since moving to Amsterdam John has performed with Joe McPhee, Han Bennink, Andy Moor, Terrie Ex, Roy Campbell, Hilliard Greene, Mike Reed, Jeb Bishop, Ab Baars, Nate McBride, Fred Lonberg-Holm, Michael Vatcher, Jason Roebke, Wilbert De Joode, Dirk Bruinsma, Jasper Stadhouders, Onno Govaert, Andrea Taeggi, Frank Rosaly, Klaus Kugel, Yedo Gibson, Renato Ferreira, Raoul van der Weide, Eric Boeren, Viljam Nybacka, Wim Jenssen, Oscar Jan Hoogland, Ivo Bol, Alfredo Genovesi, Meinrad Kneer, Gerri Jager, Stevko Busch, and numerous other musicians from the Dutch and international improvisation scene."

"Raoul van der Weide (Fontenailles / Fr, 1949) played 6 years of classical violin in the Northern Netherlands Youth Orchestra. As a bassist he developed largely autodidactic but also studied classical double bass at John Clayton and Norma Brooks. Contrast point at Guus Janssen. Feel inspired by inspiration and improvisational practice in the free but unstructured views of various musicians like Paul Termos, Guus Janssen, Lennie Tristano, Misha Mengelberg, Jimmy Giuffre, Steve Lacy, Ornette Coleman, Derek Bailey, Charles Mingus and Munir Bashir.

As an improviser, the creative focus is on the development possibilities of open personal aesthetics in the broadest sense. The continued deepening of its own sound, intonation and power of expression - of the musical fingerprint - is considered important.Van Raoul van der Weide published the solo CD 'Passages' (GeestGronden # 24 / www.geestgronden.com) at the beginning of 2006, to which De Volkskrant and promising 4 stars discussion was dedicated.

Worked together in Bert Koppelaar's POINT OF ORCHESTURE, Paul Termos Trio, Guus Jansen Septet / Octet / Orchestra, Burton Greene Quartet / Trio Spazio Trio (with K. Bauer and Guenther Sommer), Luc Houtkamp Quartet, Ab Baars Sextet, Peter Zegveld projects ('Caspar Rapak' and 'Statua Tumultus'), The Gravitones (Winners Dordtse Jazz Prize 1995), Joost Buis & The Famous Astronotes, Sound-Lee! Quartet ('Plays the Music of Lee Konitz'), New Crosscurrents Sextet."

"Peter Jacquemyn (1963° schaarbeek) moves easily between the visual arts and music. As a sculptor he assaults tree trunks with axe and chainsaw. His concerts are just as spectacular: with unbridled energy he lovingly wrestles his double bass.It is a battle in which all means are fair: bows (1, 2 or 3), dented soda cans, plastic bags, crumpled paper, mutes, horns, retuned strings,...

All of this ranges Peter Jacquemyn among Belgium's most interesting improvisers with a very justified international reputation."

"Klaus Kugel studied at the School of Jazz in Munich. Since 1989 he attracted attention worldwide through projects with Petras Vysniauskas, Karl Berger, Tomasz Stanko, Charlie Mariano, Kent Carter, Michel Pilz, Theo Jorgensmann, Kenny Wheeler, Vyacheslav Ganelin, Bobo Stenson, Glen Moore, Steve Swell, Sabir Mateen, Robert Dick, Peter Evans, Perry Robinson, Hilliard Greene, John Lindberg, Gerd Dudek, William Parker, Bobby Few, Roy Campbell, Jemeel Moondoc, Waclaw Zimpel, Mars Williams, Charles Gayle, Conny Bauer, Ken Vandermark, Joe McPhee, John Edwards a.m.o..

Over the past 30 years, he gave numerous concerts and appeared at festivals throughout Europe, the Baltic States, Canada, USA, Syria, Japan, Mexico, Russia, China, Ukraine, Azerbaijan and Israel."
