As the son and grandson of Motown mogul Berry Gordy, Stefan and Skyler Gordy have hit-making music in their blood. The electro noise they make together as LMFAO may not exactly be the boss' cup of sweet tea, but the legendary pater familias should be proud nonetheless. As the raunchy rapping Redfoo and SkyBlu, the LMFAO pair not only score chart-toppers, but the uncle-and-nephew duo created a dumb-but-defining aesthetic with "Party Rock Anthem" and other like-minded tracks. Their brand of scorched-earth electronic bop and simple hedonistic lyrics make the Ramones look like Michel Foucault. Yet LMFAO got the last and first laugh from the looks of the crowd at the Wells Fargo Center on Saturday. Not only was the show nearly sold out, it was packed with tweens — girls and boys — dressed in their heroes' favored garb of Day-Glo colors, oversize glasses, and giant wigs.
