Bobby McFerrin: You probably recognize Bobby McFerrin and his irrepressible grin from "Don't Worry Be Happy" (and you're probably cringing at the memory of the two baggy neon-hued t-shirts you were wearing at the time). But he's not just an '80s hit - Bobby McFerrin joined the noble ranks of Those Who Alter Music History when his nimble vocal chords blasted through what used to be considered the boundaries of the human voice. Sounding in turn like a saxophone, an operatic soprano, or an avian chorus, Mr. McFerrin often performs alone onstage, singing multiple parts in a capella and providing rhythm with his voice or his body. On April 10th, he performs the American premiere of VOCAbuLarieS - his first album in eight years - in concert with the Pacific Mozart Ensemble.

April 10. Nob Hill Masonic Center, 1111 California Street. Tickets are $25-85 at (866) 920-5299.

Charlie Chaplin: Did you know that Charlie Chaplin wrote the music for his films? Neither did I. But his talents apparently extend beyond the comic genius needed to portray the Little Hobo who turns a leather shoe into a feast. Chaplin's original score will be played by the San Francisco Symphony while a rare screening of the 1925 classic The Gold Rush plays above the stage.

April 15-17. Davies Symphony Hall. Tickets are $15-130 at (415) 864-6000.

Simone Dinnerstein: By the age of 33, soon-to-be-acclaimed pianist Simone Dinnerstein hadn't yet had her big break. So she raised the money to record Bach's Goldberg Variations with Grammy Award-winning producer Adam Abeshouse for her debut album. Her initiative paid off (isn't it nice when that happens?) and The Berlin Concert hit No. 1 in its first week of sales. Known for her intelligent and emotive style, Ms. Dinnerstein has been called "the pianists' pianist of Generation X" by The New Yorker.

April 24. Herbst Theater, 401 Van Ness Ave. Tickets are $32-42 at (415) 392-4400.
