Animal Collective's Merriweather Post Pavilion was the cool kids' favorite album of 2009. The Baltimore band followed up that hit with what they called a "visual album"?their soundtrack to a 52-minute horror film called ODDSAC, which screened at the Egyptian on March 30. The music booms, reverbs, and howls along with the action in the nightmarish film, which recalls the freakiest moments of The Shining and The Texas Chainsaw Massacre, with vampires violently attacking marshmallow-roasting campers and bizarre human figures writhing around in black slime. It was 2010's The Wall, heralding a complete and dedicated fusion of song and film. ?Erin K. Thompson animalcollective.org
