Eight Gigs: Foxtails Brigade

San Francisco’s Foxtails Brigade has consistently stretched the boundaries of what it means to be a modern chamber-pop group. Its songs are sophisticated adult lullabies, some bubbling with childish exuberance, others drenched in unfiltered melancholy. Its new self-titled record not only flirts with rock elements, but is fierce and (somewhat) restrained in a totally new way, moving into rock-opera territory. Vocalist Laura Weinbach is still able to access her inner child with ease, but it sounds mature in a way that completely fits the strange rules of this brilliant band. 212 15th Street, www.hungryflies.org.
