Iron Butterfly – Evolution: The Best Of Iron Butterfly (LP Vinyl)

Heavy psych before anyone had a name for it, Iron Butterfly's late-'60s run produced one of rock's most recognizable tracks in "In-A-Gadda-Da-Vida," a 17-minute side-long odyssey that practically invented the concept of extended rock improvisation for a mass audience. This colored vinyl collection distills the band's Atco Records era, capturing the San Diego group at the pivot point where garage rock dissolved into something stranger, louder, and far more exploratory.
