They played for an hour when I saw them headline at Wally's Pub in New Hampshire in 2011 (which is pretty much a marathon set for them), but yes I agree they really need to play longer sets. This tour it makes sense they are only playing 7 songs because they are opening, but headlining they have no excuse. Still one of the best live bands around though imo and I contemplated going to the Whitechapel show in Worcester pretty much solely to see them.
4/5 Protest the Hero/Battlecross
4/9 Danny Brown
