While this year’s Grammy awards won’t have “thong type costumes” or “’puffy’ bare skin exposure” (Or will it?), Sunday’s ceremony still should provide plenty of grist for the snark mill, from Justin Timberlake’s “comeback” performance to Mumford And Sons’ potential big win. Will Chris Brown, Rihanna, and Frank Ocean scuffle on the stage? Will fun.'s "We Are Young" take the gramophone for song of the year? And just who is Ed Sheeran? The A.V. Club will be skeptically watching every step of the way, as well live-blogging the whole formal-but-not-formal affair. Join Erik Adams, Josh Modell, Genevieve Koski and myself right here this Sunday night starting at 7:45 p.m. ET for the festivities. We'll bring the beer; you bring the "Who?" comments.
