Modest Mouse performed “Dashboard” on Letterman Tuesday evening. It went off without any surprises (read as: Brock didn’t brandish a blade). Still don’t understand the two drummer set up. That might just be me pining for the days when the band was an underground phenom trio. Dave does get off his kiester to shake hands with the band at the end, though, which is increasingly rare given his age. The new Johnny inviting the comedian over to the couch?
