Sleepy Sun gets hazy at Crosstown Station tonight

​This San Francisco six-piece pays homage to the psychedelic rock that made its native city the capital of sex, drugs and jammy guitar solos in the late 1960s. It’s almost as if LSD had been spliced into the DNA of young bands in Northern California — conspiracy theorists, have at it — because all that psychedelic history is certainly at work in Sleepy Sun’s hazy atmospherics. But the band’s guitar licks owe a hefty debt to Black Sabbath and Led Zeppelin, too.
