It's always nice when the benevolent indie-radio overlords at KEXP throw a fundraising party. You get to help out the station, and a rock show is a lot more fun than sitting through a pledge drive. This year's Yule Benefit features buzzing Brooklyn band Yeasayer, whose spaced-out ritual rock rises from folky roots to atmospheric prog. Openers Feral Children combine drunk, tribal drumming with depressed rural lament, and the Valley reverently resurrect '70s garage fuzz and protogrunge.
