I already posted the disturbing music video for “Sacrilege”, the first single from the Yeah Yeah Yeahs’ upcoming fourth album Mosquito, but I also have to show you their performance of the song on Letterman last week. This is for two reasons: (1) Karen O. is giving me a serious Vera Farmiga moment with that blonde hair, and (2) OMG WATCH THE CHOIR DIRECTOR. Seriously, just wait for Broadway Inspirational Voices to kick in around halfway through the song, and then just sit back and enjoy the magic. She is officially my inspiration for the week.
