Here's another video from Liars awesome performance inside an abandoned jail for Pitchfork TV's Suveillance. In this clip, the band blow out cell doors with their Krautrock-throbbing "Proud Evolution." Like I said yesterday, this is basically the most perfectly located web performance show ever; Liars often sound like mental patients who were allowed to articulate their mental neuroses via music, so a destroyed prison is the perfect venue for these kind of freakouts.
