This weekend in the arts: Otherworldly sculptures, emerging artists, a public art legend, "whodunit" theater, jazz icons, letters to Shakespeare's Juliet and live music picks.
The multi-Grammy Award-winner will headline Saturday's benefit for the 22-year-old nonprofit, which helps homeless and at-risk youths. 'I'm very moved by what they do at Doors of Change and honored to be able to be involved,' he says.
