One word describes Anne-Marie McDermott’s fingers while playing the piano: manic. McDermott is a classical pianist with virtual power tools for hands, and her fingers move with such proficiency and energy that if you blink, you risk missing something. Her secret? Spontaneity. She doesn’t worry about the notes or details because she feels they will come through naturally—and, boy, do they. McDermott shows her passion for the black-and-whites when she plays Golijov, Mozart and Chausson on Sunday, April 7, at the Kanbar Center. Osher Marin JCC, 200 N. San Pedro Road, San Rafael. $29—$59. 5pm. 415.392.4400.
