When we last encountered Animal Collective, the band was performing before Radiohead but after Metric on Saturday at the All Points West Music Festival. Avey Tare, Panda Bear, and Geologist accomplished the Herculean feat of exciting a crowd that appeared overanxious to see Thom Yorke & Co. take the stage. Though not quite ruling the day, psychedelic indie drone-pop made its mark on five thousand, fidgeting New Yorkers.
