With its endless, droning minor-key riff and mumbled vocals, "In-A-Gadda-Da-Vida" is arguably the most notorious song of the acid rock era. According to legend, the group was so stoned when they recorded the track that they could neither pronounce the title "In the Garden of Eden" or end the track, so it rambles on for a full 17 minutes, which to some listeners sounds like eternity.
