Since 2007, ACMA has provided performance opportunities for NYC musicians in a variety of settings. During an evening featuring larger ensemble performances, the ACMA Chorus interprets Samuel Barber’s Agnus Dei and the ACMA Orchestra performs Mozart’s Piano Concerto No. 21 with three different pianists, as well as Delibes' "Flower Duet". In addition, this concert features various smaller ensemble performances. ACMA is geared towards creating a supportive environment for mostly non-professional musicians to channel and express their artistic impulses.
