A trip through Animal Collective's catalog is akin to exploring the deepest, weirdest crevices of a child's wild imagination. Since the early '00s, the Baltimore band have been coloring well outside the lines with their experimental folk and pop. One moment, Avey Tare and Panda Bear play off each other's gleeful coos in a lush field of acoustic fingerpicking ("Leaf House"); the next, they find ecstasy in a noisy squall of crackling synths ("Peacebone") and dancing pianos ("Fireworks"). But for every clanging tantrum ("Applesauce"), there's a moment of pure psych-pop bliss ("My Girls").
