In his fifth year of producing the Under the Radar Festival, downtown legend — and former artistic director of avant-performance space P.S. 122 — Mark Russell continues to gather new works from near (like Mabou Mines in the East Village and local performance artist/comic Reggie Watts) and far (such as Korea's Sadari Movement Laboratory). The fest's mission is to ensure that daring theatre gets its rightful place onstage, and the result is a 12-day, full-on, cost-friendly viewing spree that radiates from its Public Theatre nucleus out through Manhattan.
