Before Led Zeppelin, there was Iron Butterfly — these days, a very misremembered band from Los Angeles. Maybe it was the movie industry all around, but '60s garage-rock in L.A. had an expansive, almost cinematic streak. Iron Butterfly was not the most inventive band on that scene, but it became the most famous because of a single, durable, out-of-nowhere hit, "In-A-Gadda-Da-Vida." The song was 17 minutes long, and the proper thing to do on underground radio stations was the play the whole thing.
