Earth Opera was an American psychedelic rock band formed in 1967 by Peter Rowan and David Grisman, known for their innovative blend of rock, folk, and bluegrass influences. The group gained recognition for their energetic live performances and eclectic sound during the late 1960s psychedelic era before disbanding in 1970. Though short-lived, Earth Opera's experimental approach to genre fusion made them influential figures in the development of progressive and jam band music.
