This band explores the boundaries between composition and improvisation. Keefe Jackson, saxophonist and principal composer, formed the Chicago group in 2003. Fast Citizens held a residency at Chicago's famous club the Hideout, where the group developed a formidable cohesiveness. Their music has broadened, even redefined the idea of a "cooperative" band. The group includes saxophonist Aram Shelton and cellist Fred Lonberg-Holm, who also composes for the group, and cornet player Josh Berman, drummer Frank Rosaly and bassist Anton Hatwich. Berman, Jackson, and Rosaly are also members of the Chicago Luzern Exchange. "... Jackson's marbled tone expresses a lovely lyricism no matter how brusque or serrated his lines get." - Chicago Reader in 2004.
