Tommy had the dubious distinction of being the first-ever rock opera; however, it's none the worse for that, Ken Russell's adaptation notwithstanding. Due largely to Pete Townshend's skill as a songwriter and composer, Tommy tells a coherent story and includes quality rock and roll at the same time, an impressive feat by itself. While surprisingly more linear than the later Quadrophenia, Tommy boasts several songs that stand up well on their own, including the classic "Pinball Wizard," "The Acid Queen," "I'm Free," and "Sally Simpson." Much of the rest doesn't make much sense lyrically unless you listen to the entire album, but you'll probably want to do that anyway, preferably with the lights low and the stereo cranked. --Genevieve Williams
