So you’re at the bar and suddenly, the jukebox cranks out a song that inspires a fellow imbiber to passionately assert some band’s superiority over another tangentially related band. Rock and Roll Cage Match is the ideal book for such opinionated pontificators. In cogent, lively essays, stellar writers decide 30 musical feuds, some real (Jay-Z vs. Nas, Blur vs. Oasis, Lennon vs. McCartney), some creative (Simon & Garfunkel vs. Hall & Oates, Bob Dylan vs. Bob Marley). Through thoughtful execution of a risky premise, Cage Match offers semi-definitive answers for rock-geek know-it-alls, while igniting as many arguments as it settles.
