Sonic Youth's work for Starbucks is one thing, but this performance at the Santa Monica, Calif., Urban Outfitters was for a decidedly good cause. The indie rock icons joined electro-popper Dntel at the Salvation Army-influenced clothing retailer on July 21 as part of a Free Yr Radio instore to benefit Los Angeles FM station KXLU. In this clip, they neither revisit their landmark Daydream Nation nor break out new stuff from their most recent album, last year's frequently overlooked Rather Ripped.

Instead, Sonic Youth reach way back to debut LP Confusion Is Sex for "The World Looks Red", which features grotesque lyrics ("people with fish eyes") by Michael Gira. It's probably a strange feeling to play a song released 14 years ago-- back when New York was even less like Los Angeles-- at a huge retail outlet in a Southern California coastal town. But the band show no signs, jumping around as if sex wasn't confusing at all. "Yes, it is/ No, it isn't," Thurston Moore speak-sings. Wire up the radio.
