I had the pleasure of recording Petr Kotik's S.E.M. Ensemble at the Paula Cooper Gallery last night. Marcel Duchamp's “La Mariée Mise à Nu par Ses Célibataires, Même. Erratum Musical” (1922) was a highlight, as well as John Cage’s 5 unaccompanied “Solos” (1958) and Fontana Mix” (1958) being played simultaneously. Allan Kozinn wrote a nice writeup for the Times.
