Whether you need a new pair of jeans or not, this afternoon is a good time to hit the Lucky store on the Promenade, as it inaugurates its new free music and art series, the Neighborhood Social. Presented by Filter magazine, the events kick off with an acoustic set from avant-goth indie songstress Bat for Lashes, turntable love from KCRW's Jason Bentley, and sleek, topical artwork by LA-based multimedia collective Giant Artists.
