Sonic Youth have done their share of pop covers over the years. As Ciccone Youth, they wiped their dirty boots on a pair of Madonna tunes on 1988's The Whitey Album, while under the Sonic Youth moniker the band has covered artists as diverse as the Carpenters, Alice Cooper and the Kinks. Perhaps their most unlikely cover is of Plastic Bertrand's new wave novelty "Ça Plane Pour Moi" from a 1992 pro-choice compilation. It's a pretty straightforward cover, although naturally there is plenty of distortion fuzzing away in the background. Not sure the lyrics are particularly accurate, either - Thurston Moore seems to be replicating phonetics rather than the actual language. Not that it makes any difference, just thought I'd mention it to sound clever.
