Mass in F Minor is the third studio album by The Electric Prunes, released in 1968, consisting of a musical setting of the mass sung in Latin and Greek and arranged in the psychedelic style of the band. David Axelrod was hired by Reprise Records to arrange and produce the album after the group's manager David Hassinger had got them to sign the rights to their name over to Axelrod. He was given carte blanche by Hassinger to do what he wanted with the Electric Prunes.
