MUSIC: Karl Blau, Painted Cakes, Zoyres Eastern European Wild Ferment, and DJ Odd Nosdam of Anticon all perform ion Hayes Valley. But Washington-based Karl Blau is the main attraction tonight, at least according to Hiya Swanhuyser, who describes Blau as having a "wide array of influences to wind up as blissy indie-folk, full of found sounds and Brian Wilson-worthy vocal harmonies." So there you go.
