"Jeb Bishop was born in Raleigh, North Carolina during the Cuban missile crisis. He began playing the trombone at the age of 10, under the tutelage of Cora Grasser. Other influential teachers during junior high and high school included Jeanne Nelson, Eric Carlson, Richard Fecteau, Greg Cox, and James Cozart.

He majored in classical trombone performance at Northwestern University from 1980-82, studying with Frank Crisafulli. Deciding he did not want to pursue a career as an orchestral musician, he returned to Raleigh in 1982 and took up engineering studies at NC State University. Raleigh's developing underground rock scene attracted him, and from 1982-84 he played bass guitar in rock bands in the Raleigh area.

At the same time, he developed an interest in philosophy, eventually majoring in the subject, and spent 1984-85 studying philosophy at the Higher Institute of Philosophy of the Catholic University of Louvain, Belgium.

Returing to Raleigh in 1985, he spent the next few years working at menial jobs and playing guitar, bass, cheap keyboards, drums, etc., in rock bands including and/or, the Angels of Epistemology, Egg, and Metal Pitcher.

In 1989 he left Raleigh to pursue graduate studies in philosophy, first at the University of Arizona, then at Loyola University of Chicago (where he was awarded the Crown Fellowship in the Humanities). During 1991-92 he returned to Europe, spending the summer of 1991 studying German at the Goethe-Institut Iserlohn (now closed), and then pursuing independent studies in philosophy at the French-language division of the University of Louvain.

Returning to Chicago in 1992, he completed his M.A. at Loyola in 1993. By this time he had already begun to make connections with improvising musicians in Chicago, having joined the Flying Luttenbachers as bassist (later adding trombone) in late 1992, and playing guitar occasionally in a quartet with Weasel Walter, Ken Vandermark, and Kevin Drumm. Other bands during this period included the Unheard Music Quartet (with Vandermark, Mike Hagedorn on trombone, and Otto Huber on drums) and the Rev Trio (with Walter and saxophonist Joe Vajarsky). Bishop played electric bass in both these bands.

In late 1995, Bishop joined the Vandermark 5 as one of its founding members, and remained with the band through the end of 2004. During this period he also became associated with many other groups, including the Peter Brötzmann Chicago Tentet, School Days, Ken Vandermark's Territory Band, and his own Jeb Bishop Trio, and became a very frequent participant in ad hoc and free-improvised concerts in Chicago. Bishop performed in the inaugural concerts of two of the longest-running free-music concert series in Chicago: the Myopic Books weekly concerts (originally at Czar Bar; with Rev Trio) and the Empty Bottle Wednesday night concert series (with a quartet of Terri Kapsalis, Kevin Drumm, and Jim O'Rourke). He curated the monthly Chicago Improvisers Group concerts at the Green Mill from 1999-2002, and co-curated the weekly Eight Million Heroes concert series at Sylvie's in 2005-6.

Bishop has made dozens of recordings with many different groups, has toured North America and Europe many times, and maintains a busy performing schedule."

"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."

"Jason Stein was born in 1976 and is originally from Long Island, New York. Stein is one of the few musicians working today to focus entirely on the bass clarinet as a jazz and improvisational instrument. He studied at Bennington College with Charles Gayle and Milford Graves, and at the University of Michigan with Donald Walden and Ed Sarath. In 2005, Stein relocated to Chicago and has since recorded for such labels as Leo, Delmark, Atavistic, 482 Music and Clean Feed. Stein has performed throughout the US and Europe, including performances in festivals in Lisbon, Cracow, Utrecht, Barcelona, Debreccen and Ljubljana. He has had the opportunity to perform with a number of exciting local and international musicians including: Michael Moore, Jeff Parker, Oscar Noriega, Rudi Mahall, Ken Vandermark, Rob Mazurek, Jeb Bishop, Ingebrigt Haker-Flaten, Urs Leimgruber, Pandelis Karayorgis, Fred Lonberg-Holm, Tony Buck, Eric Boren, Kent Kessler, Tobias Delius, Michael Zerang, Michael Vatcher, Peter Brotzman, and Wilbert DeJoode."

"Keefe Jackson, saxophonist/clarinetist/improvisor/composer, arrived in Chicago in 2001 from his native Fayettevile, Arkansas. He performs regularly in the U.S. and in Europe with many musicians including Pandelis Karayorgis, Tomeka Reid, Tim Daisy, Dave Rempis, Jeb Bishop, Jason Roebke, Jason Adasiewicz, Mike Reed, Jason Stein, Josh Berman, Fred Lonberg-Holm, Frank Rosaly, Oscar Jan Hoogland and Marc Unternaehrer. He has also appeared with Michael Moore, Ab Baars, Michiel Braam, Satoko Fujii, and Anthony Coleman. Bill Meyer (Chicago Reader): "...the impeccable logic of his lines and the richness of his tone leave you wanting more... Jackson's high-register squiggles and coarsely voiced, rippling runs push the limits of the tenor's tonal envelope." Frank van Herk, de Volkskrant (Amsterdam): "[Jackson] has an old-fashioned, warm-woolly sound, and a feeling for melodic lines that take their time in unfolding." He has been mentioned in the DownBeat Critics Poll in the Rising Star Tenor Saxophone category. Recordings are available on Delmark and Clean Feed Records."
