The Electric Prunes' career was emblematic of the shifting tides of rock music in the 1960s, overlapping garage rock, psychedelia, and hard rock during their initial 1965-1970 run. Their early records were high-powered garage rock with a psychedelic bent fueled by creative use of fuzz, reverb, and studio trickery. After hitting with “I Had Too Much to Dream (Last Night)” and “Get Me to the World on Time” in 1967, the group released two albums in a similar vein before record company politics intervened and they became a vehicle for producer David Axelrod to explore orchestrated psychedelia on 1968's Mass in F Minor. No original members of the group remained when they folded in 1970, but many of the founders were on board when the Prunes re-formed in 1999. 2021’s Then Came the Dawn: The Complete Recordings 1966-1969 is a comprehensive collection that documents the group's tumultuous first era.
