Oakland experimental duo Grex returns to Sacramento, joined by stalwart bandleader Tony Passarell and the improvising trio of Jon Bafus (Gentleman Surfer), Jon Raskin (ROVA), and John Shiurba.

Grex is an experimental music duo based out of Oakland, California. In biological terms, a "grex" is an entity composed of several smaller organisms. Grex (the band) explores the meeting point between surreal songcraft and the dark outer reaches of free jazz, industrial hip-hop, and art rock. The group has been called an "otherworldly experience" (Eugene Weekly) and "true genre warping music" (KFJC), recalling at turns the ecstatic energy of John Coltrane, the electronic squall of Death Grips, and the lilting songwriting of Mitski.
