chapel hill Mouthus, Antennas Erupt, Mowing Lawns Nightlight-- While New York City perpetually reinvents itself as the bastion of new rock-whatever, a clutch of left-of-center young experimenters are bubbling from beneath the surface, informed by the abrasive American noise underground and the ebbs and flows of European psychedelic music. The Gotham-based duo Mouthus are in these ranks, blurting out sheets of overdriven guitar. Sacramento quartet Antennas Erupt works the fertile soil of free jazz and rock composition with cello, drums and alto sax pushing a sound that touches on both Ayler and Beefheart. Locals Mowing Lawns, with guitarist Todd Emmert, will crank things up on the squawk meter, too. --Chris Toenes durham Japanese Tea Ceremony Duke Gardens-- Celebrate the rising of the new moon with a Japanese tea ceremony demonstration and tasting with a koto and shakuhachi recital and hors d'oeuvres.
