Grains was founded in San Francisco in 2009 after drummer Marc Deriso (Cults, Japandi, Weatherbox) met guitarist Brendon Randall-Myers through a Craigslist posting entitled "Math Rock". Whether performing in dive bars, all-ages punk clubs or new music concerts, the group marries the energy and aesthetic of DIY punk to the precision and rigor of contemporary chamber music and the spontaneity of free jazz. Recently the duo has focused on collaboration with other artists and ensembles, working with guitarist George Pritzker (Japandi, Weatherbox, Realization Orchestra), tenor sax/laptop improviser Alex Christie, guitarist Bill Wolter (Slydini, Inner Ear Brigade), postclassical guitar/percussion duo The Living Earth Show, and chamber music group Nonsemble 6.
