"Jason Adasiewicz was born in Wichita, Kansas in 1977, but raised in Crystal Lake, Illinois. He studied jazz drums at DePaul University for three years. He only eased into the vibraphone after leaving school, playing it in the indie-rock scene around Chicago with bands like Pinetop Seven and the singer-songwriter Edith Frost.

In the early 2000s he began his collaboration with cornetist Josh Berman and drummer Mike Reed. Since then he was worked in the Chicago jazz and improvisation scene with multiple bands, including Rob Mazurek's Starlicker and Exploding Star Orchestra, Mike Reed's Loose Assembly, Josh Berman and His Gang, Nicole Mitchell's Ice Crystal, James Falzone's Klang and Ken Vandermark's Topology and Audio One.

Adasiewicz formed his Chicago-based jazz quintet, Rolldown, in 2004, while living in Madison. In 2008 he founded the trio Sun Rooms, with Nate McBride and Mike Reed."

"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."

"For more than fifteen years, cornetist, improviser, composer, and music presenter Josh Berman has been an essential contributor to Chicago's active improvised music scene. His work encompasses both developing opportunities for presenting improvised music, and performing in a variety of highly collaborative formats. He's a co-founder of critically acclaimed Umbrella Music, and curator of the Sunday night music series at the Hungry Brain. He's performed as bandleader of his own groups, Josh Berman Trio, Josh Berman's Old Idea, and Josh Berman and His Gang, and as co-leader of Chicago Luzern Exchange.

In addition to his work as bandleader, Berman has performed and recorded with some of the most internationally respected musicians and composers in jazz and improvised music: Bill Dixon, Ab Baars, Keefe Jackson, Joe McPhee, Jason Adasiewicz, Mike Reed, Michael Moore, Ken Vandermark, Frank Rosaly, Rob Mazurek, Jason Stein, Jeb Bishop, Dave Rempis, Michael Zerang, Fred Lonberg-Holm, and Paul Lytton. He is also a frequent collaborator with dance artists; his collaboration with dancer Ayako Kato and musician Jason Roebke was awarded a CROSSCUT grant for New Collaborations in Sound/Movement from Experimental Sound Studio and Links Hall. Berman was named in the DownBeat critics' poll among Rising Stars, Trumpet. He has toured the United States, Canada, Europe, and Japan.

In 2009, Berman and his group Old Idea released their first full length CD/LP, Old Idea, on Delmark. Josh Berman and His Gang's There Now, also on Delmark Records, came out in 2012. And 2015 saw the release of Josh Berman Trio's A Dance and A Hop on Delmark. The albums have garnered critical acclaim in publications including The New York Times, DownBeat, Jazz Times, the Chicago Reader, and the Chicago Tribune."

"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."
