Provided that CBS isn't planning a Two and a Half Men marathon, you won't find a dumber way to spend your Tuesday night than on the Denver stop of LMFAO's Party Rock Tour. But you might not find a more enjoyable way, either: On its recent major-label debut, these club-rap kings throw down a non-stop barrage of infectiously goofy rhymes over slick '80s-inspired tracks that make even less use of nuance than the stuff on the Black Eyed Peas' latest. Just as stupid but a bit more stoner-attuned, Shwayze has a new record out called Let It Beat, on which the Malibu duo joins forces with the erudite likes of Snoop Dogg, Ric Ocasek and Darryl Jenifer of Bad Brains; of course, its cover still features a bikini-clad babe without a head. Hip-hop purists up in arms over the form's transformation from socially conscious to social lubricant: This shit will infuriate you.
