This collection proves that Alice Cooper was one of hard rock’s most dynamic bands in the early ’70s. “I’m Eighteen” turns teenage alienation into a clenched fist of creepy guitar crunch and a set of pained howls, and “School’s Out” transforms those same awkward themes into an anthem of liberation as celebratory as a Broadway blockbuster. On top of all that, the smart pop hooks weave crisp Beatles-esque harmonies into the slashing glam-rocker “No More Mr. Nice Guy.”
