Formed in 1990 by saxophonists Pat Mallinger and Cameron Pfiffner, Sabertooth explores a variety of musical genres in the quartet format of two saxophones, drums (Ted Sirota) and organ (Pete Benson). The band's repertoire includes many original compositions; some inspired from various ethnic origins. In addition, the band often performs standards and jazz classics. Sabertooth continues an extended residency at one of Chicago's premier jazz clubs, the famous Green Mill Lounge. The band has been playing to capacity audiences every Saturday evening for ten years. This energy is represented on Live at the Green Mill, recorded June 23, 2007.
