Folk/avant-garde guitarist John Fahey recorded several songs in the early 1960s that experimented with unusual recording techniques, including backward tapes, and novel instrumental accompaniment. His nineteen-minute "The Great San Bernardino Birthday Party" "anticipated elements of psychedelia with its nervy improvisations and odd guitar tunings". Other songs from Fahey's "The Great San Bernardino Birthday Party & Other Excursions" (recorded between 1962 and 1966) also used "unsettling moods and dissonances" that took them beyond the typical folk fare. In 1967, he performed with the psychedelic/avant-garde/noise rock band Red Krayola (then Red Crayola) at the Berkeley Folk Festival which was recorded and later released as "Live 1967". Among other descriptions, their performance has been likened to early Velvet Underground bootlegs and "the very weirdest parts of late-'60s Pink Floyd pieces (like the shrieking guitar scrapes of 'Interstellar Overdrive')".
