I agree...Deerhoof absolutely SLAYED last night. It seems the loss of a guitarist opened up their ability to just go wild with a lot of the songs. And the Electric Rainbow Machine was definitely the best stage prop I've seen in a long time.
Do they have some rule about not playing "O'Malley, Former Underdog"? I've never seen it live at any post-Runners Four show. That might be my favorite song of theirs period.
