This heavy Los Angeles funk-rock band was founded by the Suicidal Tendencies duo of vocalist Mike Muir and bassist Robert Trujillo, with guitarists Adam Siegel (Excel) and Dean Pleasants, and Janes Addiction drummer Stephen Perkins. The band was deemed more than a side project for Muir and Trujillo, given equal status with Suicidal Tendencies, and the two bands often toured together, necessitating two exhausting sets per night for the pair. Their 1991 debut established an entirely different sound from the parent band, with a heavy, Red Hot Chili Peppers-style funk attack, with Muir, for once, producing lighter lyrical fare. Standout track "Therapy" featured guest backing vocals from Ozzy Osbourne, who punctuated Muirs vocals with gleeful, manic roars of the title over furious riffing and a potent Trujillo-Perkins rhythm. Perkins left for Porno for Pyros the following year, and Josh Freese stepped in on Sarsippius' Ark, an odd collection of previously unreleased songs, live takes, cover versions, and new numbers, with spoken interjections from a "Sarsippius" character. Groove Family Cyco was a more conventional set of new material in the same hard funk vein, with Muir taking a satirical lyrical swipe at Rage Against the Machine on "Do What I Tell Ya!", while adopting his more customary serious lyrical slant. The industrious Muir also formed a punk band, My Head, with Siegel, before returning to Infectious Grooves in 2000 for fourth album Mas Borracho. ~ Rovi Staff
