Before you post the final and non-retractable version of your ”2010 Songs of The Year” list, be sure to listen to What Happened?, a criminally unheard gem off Animal Collective’s score to the experimental film ODDSAC. It’s a track that mixes the reckless forward momentum of “Turn Into Something” with the electronic pallet of Strawberry Jam, Avey Tare combating a constant squeal and a relentlessly uptempo drum loop for three breathtaking minutes. Tare’s on his A game here, his yelp of the title lyric warm but also shrilly desperate, Animal Collective invoking its trademark brand of nostalgia and adding something sinister. “What happened to make me suffer inside?” goes the opening lyric. Who knows exactly, but looking at the wild party scene the song accompanies, my guess is growing old happened, and youth is now a hazy, hallucinatory memory of constant abandon. Not to be missed.
