(MUSIC) What can't San Francisco's John Dwyer do? From the spaz-punk of Pink & Brown through the electro-shock techno of Zeigenbock Kopf and the gutter-garage freakouts of Coachwhips, the guy is well versed in nearly every style of art-damaged music. With OCS, he's more restrained, partnering with Patrick Mullens to tweak old-timey folk and death-letter blues into a lo-fi concoction that ambles along as gently as creek water-creek water that's occasionally polluted by psychedelic flying-saucer landings.
