In-A-Gadda-Da-Vida by Iron Butterfly (Atco, 1968)
From the album, In-A-Gadda-Da-Vida, and at over 17 minutes, In-A-Gadda-Da-Vida the single takes up the entire second side of the album. The single ended up at #30 in the U.S.
This single continued the trend that the music of Blue Cheer, Jimi Hendrix and Steppenwolf were paving: psychedelic music was fusing into heavy metal music. In 2009, VH1 named it the 24th Greatest Hard Rock Song of All Time.
The two commonly held beliefs about the song’s unusual title: It was originally titled “In the Garden of Eden,” but after a bit of alcohol consumption, singer Doug Ingle slurred the words and the song was reborn as In-A-Gadda-Da-Vida. The other belief is drummer Ron Bushy was listening to it through headphones and that he was the one responsible for writing down the slurred title because he couldn’t make out what Ingle had said.
