The Santa Rosa Symphony this weekend presents a program of American composers including Barber and Copland, but all eyes these days are on Elliott Carter. Few people live to be 101 years old, but Carter, still alive and active in his Manhattan apartment, is defying the wheels of time past the centennial mark. Not that his age should steal the attention from his compositional powers, which over the years successfully adapted to the modernistic touches of the late 20th century with acumen and skill. In 1944, Carter was commissioned a piece to celebrate the liberation of Paris in World War II; the resulting “Holiday Overture” is a layered and optimistic work, to be performed this weekend. With guest conductor JoAnn Falletta conducting Michael Ludwig in John Corigliano’s perennial favorite “The Red Violin Concerto,” on Saturday–Monday, Jan. 23–25, at the Wells Fargo Center. 50 Mark West Springs Road, Santa Rosa. Saturday, 2pm and 8pm; Sunday, 3pm; Monday, 8pm. $10–$42. 707.546.8742.
