Earth Opera was an American psychedelic rock group, active during 1967-1969 and featuring Peter Rowan and David Grisman. Both Rowan and Grisman were virtuoso folk and bluegrass performers in Boston clubs, who became caught up in the changes in the music scene in the mid 1960s. They formed Earth Opera in 1967 in Boston, Massachusetts, and were joined by John Nagy on bass, Paul Dillon on drums, and Bill Stevenson on keyboards and vibraphone.
