"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."

"Kent Kessler (born January 28, 1957 in Crawfordsville, Indiana) is an American jazz double-bassist, best known for his work in the Chicago avant-garde jazz scene.

Kessler, born in Crawfordsville, Indiana, grew up on Cape Cod and began playing trombone at age ten. He and his family moved to Chicago when he was 13, and a few years later Kessler became intensely interested in jazz. While attending St. Mary Center for Learning High School, he began taking lessons from Kestutis Stanciauskas (Streetdancer) in electric bass and jazz theory in the middle of the 1970s. In 1977 he formed the ensemble Neutrino Orchestra with percussionist Michael Zerang and guitarists Dan Scanlan and Norbert Funk. He spent three months in Brazil during 1980-81 and spent time studying intermittently at Roosevelt University in Chicago; he and Zerang also formed a group called Musica Menta, which played regularly at Link's Hall.

Kessler began playing double bass in the 1980s and it became his primary instrument when he was asked in 1985 to join the NRG Ensemble, who toured Europe and recorded for ECM Records under the leadership of Hal Russell until his death in 1992. In 1991, he gigged with Zerang and guitarist Chris DeChiara; in need of a hornist, they called Ken Vandermark, who had been considering leaving the Chicago scene. Kessler and Vandermark would go on to collaborate extensively on free jazz and improvisational projects such as the Vandermark 5, the DKV Trio and the Steelwool Trio. In the 1990s and afterwards he worked with Chicago musicians such as Hamid Drake, Fred Anderson, and Joe McPhee, and also with European musicians such as Peter Brötzmann, Mats Gustafsson, Misha Mengelberg, and Luc Houtkamp.

In 2003, Kessler released a solo album, Bull Fiddle, on Okka Disk. Kessler performs alone on nine of the twelve tracks, and with Michael Zerang on three."

"Born in Warwick, Rhode Island on September 22nd, 1964, Ken Vandermark began studying the tenor saxophone at the age of 16. Since graduating with a degree in Film and Communications from McGill University during the spring of 1986, his primary creative emphasis has been the exploration of contemporary music that deals directly with advanced methods of improvisation. In 1989, he moved to Chicago from Boston, and has worked continuously from the early 1990's onward, both as a performer and organizer in North America and Europe, recording in a large array of contexts, with many internationally renowned musicians (such as Fred Anderson, Ab Baars, Peter Brötzmann, Tim Daisy, Hamid Drake, Terrie Ex, Mats Gustafsson, Devin Hoff, Christof Kurzmann, Fred Lonberg-Holm, Joe McPhee, Paal Nilssen-Love, Paul Lytton, Andy Moor, Joe Morris, and Nate Wooley). His current activity includes work with Made To Break, The Resonance Ensemble, Side A, Lean Left, Fire Room, the DKV Trio, and duos with Paal Nilssen-Love and Tim Daisy; in addition, he is the music director of the experimental Pop band, The Margots. More than half of each year is spent touring in Europe, North America, and Japan, and his concerts and numerous recordings have been critically acclaimed both at home and abroad. In addition to the tenor sax, he also plays the bass and Bb clarinet, and baritone saxophone. In 1999 he was awarded the MacArthur prize for music."
