Iron Butterfly

Iron Butterfly was a psychedelic rock band from the sixties considered to be the first metal band of all time. They are best known for their hit In-A-Gadda-Da-Vida, which is over ten minutes long. It was especially popular with those tripping on acid. There is a much shorter single version at about two minutes. The song was originally going to be called "In the Garden of Eden", but had its name changed due to the slurred vocals of the lead singer. The actual Hall of Fame has considered Iron Butterfly, but not inducted them. The single version of In-A-Gadda-Da-Vida has become a classic rock staple.
