One nifty side effect of the ostensible garage-rock revival is that major labels are actually signing scruffy, no-frills guitar bands again. Aussie quartet Jet wear their influences on their chests and faces, sporting AC/DC tees and half-ass beards. Though there's a ballad or three here, the overall aesthetic is young, loud, and snotty. Whaddya expect, with song titles like ''Are You Gonna Be My Girl?'' and ''Cold Hard Bitch''? Aw, yeah -- they're dirty, sweet, and they're our boys.
