Filthy Friends (photo: Ian Young) They call themselves Filthy Friends, but they could just as well call themselves Filthy Supergroup of Supershredding Indie Guitar Rock Friends. Featuring Sleater-Kinney's Corin Tucker, R.E.M.'s Peter Buck and band members from Minus 5 and King Crimson, Filthy Friends crammed a whole host of six-strings on the small Swedish stage for an evening of rollicking riffs and protest songs. The band's second album, Emerald Valley, is out now on Kill Rock Stars.
