It's hard to tell what, exactly, is going on in director Jack Kubizne's video for Animal Collective's "Brother Sport", our #23 track of 2009. At certain points, the hallucinatory clip is the story of two modern-primitive kids and a dog, who tear around a trailer park and stage a fingerpainting rave in a backwoods hut. At other points, it's a particularly acid-fried take on vintage 1970s Saturday morning cartoons. And for one particularly queasy stretch, it's a montage of multicolored black-lit eggs falling from the sky.

In other words, it's an Animal Collective video, and you're going to stop whatever you're doing and watch it right now.
