"Scott Fields (born September 30, 1952 in Chicago, Illinois) is a guitarist, composer, and bandleader. He is best known for his attempts to blend music that is composed and music that is written and for his modular pieces (see 48 Motives, 96 Gestures and "OZZO"). He works primarily in avant-garde jazz, experimental music, and contemporary classical music.

Fields was born and raised in Chicago, Illinois. He started as a self-taught rock musician but soon was influenced by the musicians of the Association for the Advancement for Creative Musicians (AACM), which was active in the Hyde Park neighborhood in which he grew up. Later he studied classical guitar, jazz guitar, music composition, and music theory. In 1973 Fields co-founded the avant-garde jazz trio Life Rhythms. When the group disbanded two years later, he played sporadically but soon was institutionalized for an extended period. He almost quit music until 1989.

Since then he has performed and composed actively. His ensembles and partnerships have included such musicians as Marilyn Crispell, Hamid Drake, John Hollenbeck, Joseph Jarman, Myra Melford, Jeff Parker, and Elliott Sharp."

"Jeff Parker (born April 4, 1967) is an American jazz and rock guitarist based in Los Angeles. Parker is best known as an experimental musician, working with avant-garde electronic, rock, and improvisational groups.

Parker currently plays guitar in the post-rock group Tortoise and also was a founding member of the ensembles Isotope 217 and the Chicago Underground Trio in the 1990s and early 2000s. He is also a member of the Association for the Advancement of Creative Musicians, as well as working with musicians George Lewis, Ernest Dawkins, Brian Blade, Joshua Redman, Fred Anderson (musician) and Jason Moran. He has released three solo albums: Like-Coping, The Relatives and Bright Light in Winter."

"Jason Roebke is a double bassist, improviser and composer living in Chicago. He was born and raised in tiny Kaukauna, Wisconsin in 1974 and began playing electric bass at age 14. His first fascination was with Motown bassist James Jamerson. Roebke's first introduction to jazz was at a summer jazz camp run by local legend, pianist, John Harmon. Here he heard recordings of Charlie Parker and a life long fascination with music was begun. His high school band director had a small jazz CD collection which included Ornette Coleman's "The Art of the Improvisers" and Charles Mingus "Mingus Ah Um" which he listed to endlessly for years.

Entering college at the University of Minnesota for an extremely short stay, he returned to Wisconsin, graduating from a small liberal arts university in 1996. Roebke moved to Madison, WI to study with legendary saxophonist and composer Roscoe Mitchell. There he worked as Mitchell's music copyist for 18 months, spending nearly everyday at Mitchell's home reworking orchestral and chamber music scores with the composer. In 1998, Roebke entered the University of Michigan where he studied with bassist Rodney Whitaker.

In 1999, Roebke moved to Chicago and quickly began working with a new crop of young improvisers. There were early associations with saxophonists Aram Shelton, Dave Rempis and Matt Bauder (also a Michigan alumnus); drummers Tim Daisy and Frank Rosaly and cornetist Josh Berman. Soon after his arrival in Chicago, Roebke organized his first quartet with Bauder, guitarist Jeff Parker, and drummer Chad Taylor. He also began playing with a large improvising ensemble Chicago Improvisers Group with Ken Vandermark, Jeb Bishop, Michael Zerang, Jim Baker among others. He made his first recording as a leader in 2003 with "Rapid Croche" on 482 Music. A trio session with saxophonist Aram Shelton and drummer Tim Daisy, the recording was a critical success. Also during this time, Roebke began his long and continuing association with Fred Lonberg-Holm. Roebke played, toured and recorded with Lonberg-Holm's Terminal 4 and Valentine Trio. Roebke was the instigator of three recordings and a tour with the improvising trio tigersmilk, with cornetist Rob Mazurek and Vancouver drummer Dylan van der Schyff.

In recent years, Roebke has been playing with Jason Adasiewicz's Rolldown, Jason Stein Trio, Jeb Bishop Trio, James Falzone's KLANG, Jorrit Dijkstra's Flatlands Collective, Pillow Circles, and The Whammies, Keefe Jackson, and Mike Reed's People, Places, and Things. The trio of Nate Wooley, Fred Lonberg-Holm and Roebke released two recordings "Throw Down Your Hammer and Sing" and an untitled LP. Roebke and Berlin-based tenor saxophonist Tobias Delius released a duo CD on Nottwo Records in 2012."

"Hamid Drake (born August 3, 1955) is an American jazz drummer and percussionist. He lives in Chicago, IL but spends a great deal of time touring worldwide. By the close of the 1990s, Hamid Drake was widely regarded as one of the best percussionists in jazz and avant improvised music. Incorporating Afro-Cuban, Indian, and African percussion instruments and influence, in addition to using the standard trap set, Drake has collaborated extensively with top free-jazz improvisers. Drake also has performed world music; by the late 70s, he was a member of Foday Musa Suso's Mandingo Griot Society and has played reggae throughout his career.

Drake has worked with trumpeter Don Cherry, pianist Herbie Hancock, saxophonists Pharoah Sanders, Fred Anderson, Archie Shepp and David Murray and bassists Reggie Workman and William Parker (in a large number of lineups)

He studied drums extensively, including eastern and Caribbean styles. He frequently plays without sticks; using his hands to develop subtle commanding undertones. His tabla playing is notable for his subtlety and flair. Drake's questing nature and his interest in Caribbean percussion led to a deep involvement with reggae."
