On Animal Collective’s latest album, Strawberry Jam, it sounds as if the members of the band have swapped their Incredible String Band LPs for ­minimal-house singles and their acoustic guitars for samplers. But just because the band has gone electronic doesn’t mean that it’s given up on the major earmarks of its folky past—particularly, ­jamming. Animal Collective has never been big on meticulously reconstructing its hit songs on stage; instead, the band’s shows have a tendency toward tangents and improvisation. Not that the band will be pictured on the cover of Relix any time soon: Animal Collective’s explorations are more about delay pedals, yodeling, and tribal rhythms than mandolin-fueled grandstanding. Sure, the same could be said about Rusted Root, but in that case it wouldn’t be a compliment. Animal Collective performs at 10 p.m. at the 9:30 Club, 815 V St. NW. $12. (202) 393-0930.
