"John Zorn (born September 2, 1953) is an American composer, arranger, producer, saxophonist, and multi-instrumentalist with hundreds of album credits as performer, composer, and producer across a variety of genres including jazz, rock, hardcore, classical, surf, metal, klezmer, soundtrack, ambient, and improvised music. He incorporates diverse styles in his compositions which he identifies as avant-garde or experimental. Zorn was described by Down Beat as "one of our most important composers".

Zorn established himself within the New York City downtown music movement in the mid-1970s performing with musicians across the sonic spectrum and developing experimental methods of composing new music. After releasing albums on several independent US and European labels, Zorn signed with Elektra Nonesuch and received wide acclaim with the release of The Big Gundown, an album reworking the compositions of Ennio Morricone. He attracted further attention worldwide with the release of Spillane in 1987, and Naked City in 1989. After spending almost a decade travelling between Japan and the US he made New York his permanent base and established his own record label, Tzadik, in the mid-1990s.

Tzadik enabled Zorn to maintain independence from the mainstream music industry and ensured the continued availability of his growing catalog of recordings, allowing him to prolifically record and release new material, issuing several new albums each year, as well as promoting the work of many other musicians. Zorn has led the hardcore bands Naked City and Painkiller, the klezmer/free jazz-influenced quartet Masada, composed over 600 pieces as part of the Masada Songbooks that have been performed by an array of groups, composed concert music for classical ensembles and orchestras, and produced music for opera, sound installations, film and documentary. Zorn has undertaken many tours of Europe, Asia, and the Middle East, often performing at festivals with many other musicians and ensembles that perform his diverse output.

Zorn's compositions cross many genres and he has stated "All the various styles are organically connected to one another. I'm an additive person-the entire storehouse of my knowledge informs everything I do. People are so obsessed with the surface that they can't see the connections, but they are there." For Zorn "Composing is more than just imagining music-it's knowing how to communicate it to musicians. And you don't give an improviser music that's completely written out, or ask a classical musician to improvise. I'm interested in speaking to musicians in their own languages, on their own terms, and in bringing out the best in what they do. To challenge them and excite them." "

"Cellist Jay Campbell has been recognized around the world for approaching both old and new works with equally probing curiosity and emotional commitment. His performances have been described as "brilliant and insatiably inquisitive", "electrifying", and "prodigious" by the New York Times, and "gentle, poignant, and deeply moving" by the Washington Post. A recipient of the prestigious Avery Fisher Career Grant, Jay performed with the New York Philharmonic in 2013 and was a curator for the New York Philharmonic's 2016 Biennale. He has soloed in major venues around the globe including Carnegie Hall's Stern Auditorium, Avery Fisher Hall, and Lucerne's KKL and performed recitals in Carnegie's Weill Hall, the Kennedy, Mondavi, and Krannert centers. Dedicated to introducing audiences to the music of our time, Jay has worked closely with some of the most creative minds of the 20th/21st centuries including Pierre Boulez, Elliott Carter, Matthias Pintscher, Kaija Saariaho, and countless others from his own generation. His close association with John Zorn has resulted in over a dozen works written for him including The Aristos, a Pulitzer Prize runner up ­­resulting in the release of Hen to Pan (Tzadik), listed in the New York Times Best Recordings of 2015. Forthcoming discs in '16/17 include George Perle's cello concerto with the Seattle Symphony and Ludovic Morlot, a disc of Beethoven, Debussy, Stravinsky and Pintscher (Victor Elmaleh Collection), and a disc of works commissioned for Jay by David Fulmer (Tzadik). Also beginning in 2017, Jay will be the cellist of a new piano trio with violinist Stefan Jackiw and pianist Conrad Tao. He has been a guest at the Marlboro, Chamber Music Northwest, Moab, Heidelberger­Fruhling, DITTO, and Lincoln Center festivals."

"Called "wholesome-looking" by the New York Times, violist John Pickford Richards has gained a reputation for performing new and unusual music. Before playing in JACK, he was a founding member of the ensemble Alarm Will Sound, allowing him to work closely with composers such as John Adams, Meredith Monk, and Steve Reich at venues such as Carnegie Hall, Lincoln Center, and the Holland Festival. John has appeared with bands such as the All-American Rejects, Silversun Pickups, and Grizzly Bear and has performed as soloist with the Pasadena Symphony, Armenian Philharmonic, Wordless Music Orchestra, Ossia New Music, and with the Lucerne Festival Academy Orchestra playing the solo part to Luciano Berio's Chemins II under the direction of Pierre Boulez. He holds degrees from the Interlochen Arts Academy and Eastman School of Music where his primary teachers were David Holland and John Graham."

"Praised as a "gifted, adventuresome violinist" by the Chicago Tribune and as a "remarkable, unbelievable violinist/violist extraordinaire" by the syndicated radio program Relevant Tones, Austin Wulliman has gained critical and audience attention through his "wide technical range and interpretive daring" (New Music Box) as a soloist and chamber musician. Through in-depth collaboration with performers and composers working in a panoply of aesthetic realms, Austin searches daily for the violin's voice in today's musical world.

He first forged his reputation in Chicago with the collective Ensemble Dal Niente, serving as the group's Program Director, and winning the Kranichstein Music Prize (the grand prize for interpretation) at the Darmstadt Summer Course in 2012. With Dal Niente he has collaborated with composers such as Brian Ferneyhough and James Dillon as well as recording projects with the band Deerhoof in music of Marcos Balter, and a portrait CD of sonic adventurer Aaron Einbond. Austin has performed with Dal Niente at such venues as Harvard University and Pritzker Pavilion in Millennium Park, Chicago. As an ensemble player, Austin has also been a guest artist with groups such as Eighth Blackbird, the Chicago Symphony Orchestra's MusicNow Ensemble, and the International Contemporary Ensemble (ICE).

As soloist, he has performed Kaija Saariaho's concerto "Graal Theatre" with the Aspen Festival and Northwestern University Contemporary Music Ensembles, as well as collaborating with the composer on the American Premiere of her "Calices" for violin and piano. He has also premiered violin concerti by Chris Fisher-Lochhead and Kirsten Broberg, as well as collaborating closely on solo pieces by composers Augusta Read Thomas and Lee Hyla, two essential mentoring voices in his early years in Chicago.

His debut solo release, "Diligence Is to Magic as Progress Is to Flight" was released in 2014. The album is a concert-length collaboration with the composer-improviser Katherine Young, using 4 scordatura and prepared violins and a viola in conversation with 8-channel electronics and a chamber orchestra. Wulliman worked closely with Young from the creation of materials to the completion of the work, including traditional notation and improvised material.

Austin was also a founding member of Spektral Quartet, serving as Ensemble in Residence (as well as Adjunct Instructor of Violin) at the University of Chicago from 2011-2016. Exploring both the classical string quartet repertoire beginning with Haydn and organizing a robust commissioning program, he also explored contemporary jazz styles with artists such as Miguel Zenon, Billy Childs, and Julien Labro (recording on Azica Records) and free improvisation (forthcoming release on Room 40 in collaboration with Australian experimental artist Chris Cobilis, produced by the legendary Steve Albini). Other recording projects with Spektral Quartet have included new works by Hans Thomalla and a wide sampling of young Chicago-based composers (on the Sono Luminus and Parlour Tapes+ labels) as well as a collection of "Mobile Miniatures" by over 40 American composers designed as cellular ringtones (such as David Lang, Nico Muhly, Shulamit Ran and George Lewis). With Spektral Quartet, he has performed on series such as the University Musical Society in Ann Arbor and BargeMusic as well as performing educational residencies at the New World Symphony and Stanford University.

Austin begins new adventures in fall of 2016 as violinist in the trail-blazing JACK Quartet. JACK's coming season will include such major events as the World Premiere of a new string quartet by G.F. Haas at Wien Modern, the World Premiere of Roger Reynolds' multimedia FLiGHT at the Park Avenue Armory, and a performance the complete Xenakis string chamber music at Wigmore Hall among many other adventures in exploring the voices of today's music.

Austin received his Bachelor's Degree summa cum laude from the University of Michigan, where he studied with Aaron Berofsky. He was an endowed scholar and teaching assistant to Blair Milton at Northwestern University, where he earned his M.Mus. Further studies took Austin to the Lucerne Festival Academy (under the baton of Pierre Boulez) and the Aspen Music Festival Fellowship in Contemporary Music, where he also studied privately with Paul Kantor."
