Post-election SNL has been lacking in laughs, save for a few Lonely Island clips and Kristen Wiig appearances, but the show hasn't been slouching with the bands it's been booking. This past Saturday Phoenix appeared on the show to perform tracks from their much-anticipated Wolfgang Amadeus Phoenix , and on April 11, Yeah Yeah Yeahs are scheduled to appear on the show and promote their much-loved It's Blitz!. The host will be Zac Efron, whose fans are sure to tune in and get their heads exploded. [Pitchfork]
