Ensemble Pi
socially conscious new-music group founded in 2002, features composers whose work seeks to open a dialogue between ideas and music on some of the world’s current and critical issues. For twenty years, Ensemble Pi has presented an annual Peace Project concert, commissioning new works and collaborating with visual artists, writers, actors, and journalists such as William Kentridge, Naomi Wolf and David Riker. The ensemble was in residence for four American music festivals presented by the American Composers Alliance and now collaborates with the APNM. Symphony Space presented Ensemble Pi in birthday celebrations for composers Gunther Schuller and Krzysztof Penderecki. A multi-year collaboration with composer Elias Tanenbaum resulted in a CD of his chamber music, Keep Going, released by Parma Recordings in 2010 and reviewed by Gramophone as “a touching tribute to Elias Tanenbaum that is played with conviction and verve.” It was followed by a second CD of the music Laura Kaminsky, “played with warmth and variety” (American Record Guide). Ensemble Pi is currently working on its third CD.
