In June, American Composers Orchestra (ACO) continues its commitment to serving as a catalyst for the creation and development of new orchestral music with two Readings sessions of brand new orchestral works by 14 composers hailing from across the country, held at Miller Theatre at Columbia University (2960 Broadway, NYC). ACO’s 25th Annual Underwood New Music Readings will take place on Tuesday, June 14 at 7:30pm and ACO’s third Jazz Composers Orchestra Institute (JCOI) Readings will take place on Thursday, June 16 at 7:30pm. Both Readings, during which the new pieces will be polished and performed in their entirety, are open to the public free of charge, giving audiences a chance to look behind the scenes at the process involved in bringing brand new, stylistically diverse orchestral music to life (reservations at www.americancomposers.org suggested). Both Readings are conducted by ACO Music Director George Manahan. Mentor composers for the Underwood New Music Readings are ACO's Artistic Director Derek Bermel, and composers Sarah Kirkland Snider and Stephen Hartke. Mentor composers for the JCOI Readings are Bermel, Anthony Davis, Gabriela Lena Frank, and James Newton. Newton leads JCOI as the program director. George Lewis is director emeritus. Each composer participating in these Readings receives rehearsal, reading, and a digital recording of his or her work. Review and feedback sessions with ACO principal players, mentor composers, guest conductors, and industry representatives provide crucial artistic, technical, and conceptual assistance.
