You could say Grace Kelly — born in Wellesley, raised in Brookline, now living in Dover — is a jazz saxophonist, and that would tell you almost nothing. She sings, composes and does arrangements, a hat trick for musicians.
Kelly released her first CD at age 12 and got booked at Boston’s Scullers Jazz Club at 13. She’s played Symphony Hall and before Boston Celtics games at TD Garden. Now 20, she’s performed around the world.
