Sheku Kanneh-Mason—the charmer with the cello—makes his New York recital debut with the prize-winning concert pianist Isata Kanneh-Mason, his gifted older sister. Lest you think this two-fer is unusual, there are five more musical Kanneh-Masons at various stages in their classical careers (the youngest, Mariatu, is nine). This program includes work by Beethoven, Lutoslawski, Barber, and Rachmaninoff. —L.J.
