Prepare for some incredibly "relentless fun" on this New Sounds program. Drummer Aaron Alexander and a klez-punk ensemble (who include downtown jazz/jewish music all-stars and great young players in the klezmer scene; trumpeter Frank London, reed player Greg Wall, and guitarist Brad Shepik, among others) perform live and make mayhem in the studio. On Alexander’s latest CD, “Midrash Mish Mosh,” dueling drummers pound infectious klezmer-rooted music through round holes, embracing jazz, thrash-punk, Balkan and African rhythms. The boot will conquer the sandal.
