The next event in the Santa Barbara Symphony’s ongoing live-streamed series of concerts at the Granada Theatre will take place on April 17 at 7 p.m., with an encore matinee on April 18 at 3 p.m. Music and Artistic Director Nir Kabaretti will lead the program, which features works by American composers, including Copland’s Fanfare for the Common Man and Joan Tower’s Fanfare for the Uncommon Woman, and the world premiere of the orchestral version of local composer George N. Gianopoulos’s Polarity, part of his song cycle America for voice and piano. Bass-baritone Cedric Berry will serve as soloist in Polarity, and he also will perform Copland’s Old American Songs, which includes “Simple Gifts,” “I Bought Me a Cat,” and “Zion’s Walls.” The concert also includes works by George Walker, Samuel Barber, Charles Ives, and the late Santa Barbara composer Robin Frost. Concerts are performed without an audience, and ticketholders may watch the concert live or afterward on demand. A pre-concert virtual show will include behind-the-scenes interviews and other content.
