At this point it's hard to tell when Weezer are serious. Death to False Metal is sort of a mixed bag, a collection of previously unreleased tracks that go as far back as 1998. "Turning Up the Radio" is a collaborative effort with help from fans; the rest mostly centers on tossed tracks from the Make Believe and Red Album periods. The rawest (and best) material here is premillennial in origin: the snotty metal of "Everyone," the edgy pop of "Trampoline," the vulnerable balladry of "Losing My Mind." Then there's that pop-metal cover of Toni Braxton's "Un-Break My Heart." False metal irony?
