Since forming last summer, Hi-Fidelity, Thursday, June 7, at the 15th Street Tavern, with the Gravity Index and Los Federalis, has become one of Denver's more appealing arbiters of the garage-rock gospel. Fronted by vocalist/guitarist Joaquin Liebert, the band's live set is peppered by a batch of irresistibly crunchy pop tunes that rattle with all of the clamor and hookdom of rock and roll's glory days. The band's new CD, Adventures on Planet Heartbreak, sounds similar to something that was actually recorded in a garage -- in the backseat of an old Chevy, maybe. Despite the poor sound quality, the sheer force of songwriting talent captured on the disc is enough to make a believer out of fans of local outfits like the Down-N-Outs and the Volts. Though Hi-Fidelity channels Iggy Pop and Mick Jones with equal, loving abandon, the band nevertheless creates an explosive little something all its own.
