Tom Murphy is everywhere. You can't turn around without seeing him front and center at a local rock show, absorbing sounds and impressions -- data that he relays to All Need Is Music. Founded in 2003, the thick, photocopied zine is nearly encyclopedic in scope, with comprehensive interviews of Denver bands that sometimes run to dozens of pages. Underpinning his knack for pure information, though, is a consuming passion for Colorado music; in fact, he's currently working on a book that will document its history from 1976 to today. Where others skim the surface, Murphy digs deep -- and in doing so, renders All Need Is Music the bible (or at least the Big Takeover) of the Denver rock scene.
