Ray Angry, a keyboardist best known for his work with hip-hop collaborative The Roots, will debut “BLACK POWER~ATHENA,” at the Lexington Symphony.

The composition premieres Nov. 19 at 7:30 p.m. at Cary Hall, 1605 Massachusetts Ave., as part of a wider performance including works by Mozart and Tchaikovsky. Tickets are $15-$65 and can be purchased at LexingtonSymphony.org or by calling 781-523-9009.
