Henry Threadgill Zooid is a pioneering ensemble led by Pulitzer Prize-winning composer and saxophonist Henry Threadgill. Formed in the early 2000s, Zooid is known for its distinctive instrumentation—often featuring tuba, cello, guitar, and drums—and its innovative approach to composition and improvisation. Threadgill employs a unique system where each musician is assigned a specific set of intervals, allowing for contrapuntal improvisation within a structured framework. This method fosters a dynamic interplay among the musicians, creating complex, layered textures that are both spontaneous and meticulously crafted. The ensemble's music blends elements of jazz, classical, and avant-garde traditions, characterized by shifting meters, intricate rhythms, and a deep sense of groove. Zooid has been a central vehicle for Threadgill's artistic expression, earning critical acclaim and contributing significantly to contemporary jazz.
