In 1969 and the early 1970s, the song "21st Century Schizoid Man" by King Crimson is notable for its heavily distorted vocals sung by Greg Lake. The songs "Iron Man" by Black Sabbath and "One of These Days" by Pink Floyd both contain brief passages of ominously-growled, low-pitched vocals (in both cases studio-manipulated) against a heavy background of rock riffs. Other examples are Roger Waters' screams in some Pink Floyd songs, such as "Take Up Thy Stethoscope and Walk" (1967) and "Careful with That Axe, Eugene" (1968). Punk rock bands like The Clash, Stiff Little Fingers, and 999 also regularly employed gruff-sounding vocals, although not as pronounced as the death growl common in metal music today. The low, raspy, aggressive pitch of Lemmy Kilmister from Motörhead was not unlike the death growl and may be thought of as a precursor to the current style. Kate Bush employed raspy, guttural vocals on the track "Get Out of My House" from her 1982 album "The Dreaming".
