San Francisco’s Assemble Head in Sunburst Sound is a soundtrack for strange days and futures bright and bleak. But there is also a crooked thread that runs backward through every Assemble Head record—the celestial trajectories of The Notorious Byrd Brothers and circa ‘70 Floyd; the dusty canyon stomps of Crazy Horse, slashing action pop of the savage young Who, Italian bastardizations of Lalo Schifrin cop movie scores, and the scuzz-bomb shrapnel of latter-day garage mongers like Mudhoney and Monoshock.
