"The album, released in July 1972, is comprised of two extended instrumental pieces and two shorter songs. "Big Swifty," a theme-and-solos showcase, would become a live favorite, but the highlight came in the form of the orgiastic title track ... His writing and recording technique had matured a lot in very little time. The dirty blues jamming of the 1970 LP [Hot Rats] was replaced by clean, crisp jazz improvisations - no need to say this was also an abrupt change in style from the Mothers' 1969-1971 incarnation".
