Blog readers had so many options on Friday night in L.A. — Passion Pit, Lykke Li, SVIIB and Black Moth Super Rainbown all in town — and still the ticketless masses chose the Wiltern sidewalk for even a shot at getting into Animal Collective’s sold-out show. Hey, they are popular band. It looks like whoever made it inside really enjoyed “Brothersport.” And Animal Collective’s made no secret about how much inspiration Stereofave Grouper was to the making of Merriweather, so there’s a nice symmetry to her opening the show. (Before the comment party begins, let the record reflect that Avey has an electric guitar up there; you may now argue about whether the rest constitutes conventional instrumentation or playing, or whether or not you like Geologist’s shirt, or maybe even not argue at all! It’s summertime.) Enjoy the pics by photographer Andrew Youssef.
