Slipknot performed at Monsters of Rock 2013 in São Paulo, Brazil this past weekend, and the performance was broadcast live, so naturally it's on YouTube now. We've put together a playlist that contains almost their entire set (we couldn't find clips of "Psychosocial," "(sic)," or "People = Shit," sorry), and you can watch it above now!
