Iron Butterfly

Iron Butterfly will forever be known for ushering in the long drum solo with "In-a-Gadda-Da-Vida," which stayed on the charts for nearly three years and became one of the first million-sellers of the rock and roll era. The song is seventeen minutes long, and the drum solo is two-and-a-half minutes long. Its style, while not powerful in comparison to today's sound, was really unusual in 1968. The title is a corruption of the phrase "in the garden of Eden." Along with Blue Cheer and Vanilla Fudge, Iron Butterfly epitomized the moment that the lightness of psychedelia became heavy rock, a process later institutionalized by Led Zeppelin.
