This is one of the many reasons that these guys are one of my favorite bands. Over the holiday weekend they headlined the BottleRock Festival in Napa Valley. At the end of their set, the festival promoters cut the power.

Apparently there is a strict 10 p.m. sound curfew for the festival. At 10, the promoters cut the power to the main P.A. system. However, even losing power can't keep Dave Grohl and the guys from doing what they do best. They kept playing and the crowd joined in.
