History

Iron Butterfly are known above all for one song that filled an entire side of an LP. The band formed in San Diego in the mid-1960s, moved into the Los Angeles club circuit and recorded for Atco. Their sound put Doug Ingle's churchy, sustained organ and deep baritone at the centre, over thick fuzz guitar and a heavy, plodding rhythm section. Heavy, the debut, already leaned on that weight. In-A-Gadda-Da-Vida made it famous: the title track runs about seventeen minutes, built on a lumbering riff, with a long drum solo, organ passages that drift toward mock-liturgical territory, and a return to the riff that feels like a slow landing. The record became one of the defining albums of the psychedelic era and a regular reference in talk about the roots of hard rock and heavy metal. Ball followed with shorter, more melodic songs. A listener recognises the band by that organ tone, the slow grinding riffs, and a willingness to stretch a simple idea as long as the groove will hold.
