American Hi-Fi's 13-song debut album runs the gamut from booming, bubblegummy rock with edgy undertones ("Surround") to infectious, Offspring-like pop punk ("Flavor of the Weak "). Muscular guitars create an arena-rock feel, while producer Bob Rock (Metallica, the Cult) helps make the group's stylistic shifts seem smooth as they move from the metallic "My Only Enemy", which sounds like a more organic Nine Inch Nails, to near Nirvana on "Hi-Fi Killer". American Hi-Fi cranks out delectable ear candy for fans of pure guitar-driven power-pop, and frontman Stacey Jones is a gem of a singer-songwriter-guitarist. --Katherine Turman
