Touring heavily and releasing a blistering opening salvo of classic records, Cheap Trick rose to great success, but at the height, Petersson became disenchanted and left the band immediately after Trick completed the radical All Shook Up with Sir George Martin. Petersson ironically pulled a Yoko move -- leaving Trick to work with his wife Dagmar on Tom Peterson and Another Language (Petersson dropping the extra pseudo-Swedish 's' from his name). This mini-album of new wave wildness was the only thing heard from Petersson until he spilled beer in Nielsen's lap at a Duran Duran birthday party some years later.
Petersson rejoined Cheap Trick for a commercial, if not thoroughly artistic, return to form, Lap of Luxury. Petersson also worked with Concrete Blond and Precious Metal. In the '90s, Cheap Trick's star fell again and the quartet almost quit releasing new material, but still performed constantly. While living in Nashville, Petersson hooked up with multi-instrumentalist neighbor Doug Powell and the two joined the quasi-supergroup Swag which included Jerry Dale McFadden of Sixpence None the Richer, Robert Reynolds (the Mavericks), and Ken Coomer of Wilco. Oddly, Petersson threatened legal action against Swag in 2001 concerning membership, although his status with Cheap Trick was never in question. Petersson invented the massive 12-string bass which services distinguished clientele like Jeff Ament. ~ Doug Stone, Rovi
