Iron Butterfly

Iron Butterfly was an American rock band that played an important role in the commercialization of album-oriented rock in the late Sixties. Their only major hit song, "In-A-Gadda-Da-Vida," with a running time in excess of seventeen minutes, occupied one full side of their album of the same name. That album, released in July 1968 on [Atlantic Records]' ATCO label, has been claimed by the group and its record company to be the first to sell a million units. The RIAA did not have an official "Platinum" certification at the time, but has since awarded it "4x Multi-Platinum" status.
