The ACO is solely dedicated to the creation, performance, preservation, and promulgation of music by American composers, the only such orchestra in the world. To date, ACO has performed music by over 500 American composers, including over 100 world premieres and new commissions. In the 1990s, the ACO added new initiatives such as the Underwood New Music Readings, for young composers to hear their works rehearsed and recorded, and the 'Sonidos de las Américas' festival, focused on Latin-American music. Robert Beaser was the ACO's composer-in-residence from 1988 to 1993, then had the title of artistic adviser through January 2001, at which time he took the title of artistic director. Beaser now has the title of artistic director laureate of the ACO. Derek Bermel was the ACO's composer-in-residence from 2006 to 2009, and is now the ACO's artistic director.
