Iron Butterfly is a Psychedelic Rock band and a major influence on Heavy Metal. They are well known for "In-A-Gadda-Da-Vida", the title track of their second album. The 17 minute long piece was epic, menacing and altogether awesome, and has since become a staple of numerous pop culture references thereafter. Oh yeah, and they did some other songs, too.
Iron Butterfly released six studio albums between 1968 and 1975, and two live albums.
- Heavy (1968)
- In-A-Gadda-Da-Vida (1968)
- Ball (1969)
- Metamorphosis (with Pinera & Rhino) (1970)
- Scorching Beauty (1975)
- Sun and Steel (1975)
Iron Butterfly provides examples of the following tropes:
- Cover Version: "Get Out Of My Life, Woman" (from Heavy) is in fact a cover of an Allen Toussaint tune.
- Epic Rocking: "In-A-Gadda-Da-Vida", which is 17 minutes long. Some live versions of this song go on for even longer — reaching over 19 minutes.
- Heavy Metal: Sometimes considered a pioneer of the genre, though they don't sound quite like most later bands. They were influential on many bands, though.
- Mohs Scale of Rock and Metal Hardness: Usually between 3 and 5, but occasionally lower. They were considerably harder for their day, though...
- Mondegreen: The title of "In-A-Gadda-Da-Vida" is a Ascended Mondegreen. It was originally supposed to be "In The Garden Of Eden" (meaning, Bart Simpson wasn't far off). Doug Ingle wrote down the title for the song while severely sleep-deprived and drunk on bottom-shelf wine and decided he liked the nonsense-word title better.
- New Sound Album: Metamorphosis had some acoustic elements and a more layered production than preceding albums. Scorching Beauty and Sun And Steel were more straightforward Arena Rock / Hard Rock and are often forgotten by fans.
- Ominous Pipe Organ: "In-A-Gadda-Da-Vida", again.
- Psychedelic Rock: Of the particularly loud and heavy variety.
- Revolving Door Band: 6 different lineups from 1966-1971, 22 different lineups from 1974-1985, and 22 again from 1987 to 2012 (when they disbanded). Their last lineup was their longest-lasting: Seven years. Most didn't even last one.
- Textless Album Cover: Metamorphosis.
