1969’s best selling album (in the US), was also the second studio effort by San Diego psychedelic rock Gods, Iron Butterfly. In-A-Gadda-Da-Vida, the song, occupies the entire second side of the record, and clocks in at a whopping 17:05. Atlantic Records wouldn’t see a more successful album until the release of Led Zeppelin’s IV in 1971. Which begs the question, why has it taken me so long to obtain this piece of modern rock history?!
