The video for “Sad Song” by Brooklyn synth-pop trio Au Revoir Simone features the gals making frosted cookies for some sort of sad birthday party, and both the song and video are irresistible. My brains liquify and run out my ears when the fog machine starts up. And dig the wild choreography! Au Revoir Simone performs this Friday, May 29 at the Music Hall of Williamsburg. See you there!
