Unofficially, this is Michael Nyman Week in Mexico City. While he is primarily known as a composer, Nyman, a part-time resident of Mexico City, is also a photographer and director of experimental films. On Wednesday the 24th at 7 pm, an exhibition of photos he took and a short film he shot inside the Cine Opera -- a crumbling wreck of a movie theatre that has been closed for years -- opens at the Museo Universitario del Chopo (Calle Dr. Enrique González Martínez 10, Colonia Santa María la Ribera). The following night, the 25th, he will be playing a concert entitled "The Piano Sings," which includes various of his compositions, among them scores to his own films (which will be shown) at the Teatro de la Ciudad Esperanza Iris (Calle Donceles 36, Centro Histórico).
