About Cactus

Cactus is the debut studio album by American rock band Cactus, released on July 1, 1970, by Atco Records. The eight tracks consist of six original songs written by the band, plus covers of Mose Allison's version of blues standard "Parchman Farm", and Willie Dixon's "You Can't Judge a Book by the Cover". The introduction to the track "Let Me Swim" loosely inspired the first few seconds of the 1978 instrumental "Eruption" by Van Halen.
