Sleepytime Gorilla Museum

Avant-Garde Experimental Rock Ensemble

Sleepytime Gorilla Museum was an avant-garde rock band that formed in 1999 in Oakland, California. The group was known for its experimental and eclectic style, which blended elements of progressive rock, heavy metal, and performance art. The band's lineup included Nils Frykdahl, Dan Rathbun, Carla Kihlstedt, Matthias Bossi, and Michael Mellender, each of whom brought a diverse range of musical influences and talents to the ensemble. Sleepytime Gorilla Museum's live performances were theatrical events that often featured homemade instruments and elaborate stage shows. They released three studio albums during their active years: "Grand Opening and Closing" in 2001, "Of Natural History" in 2004, and "In Glorious Times" in 2007. The band announced their final show in 2011 and have since been inactive as a group. Their work continues to be celebrated for its innovation and unique contribution to the progressive music scene.
