Tuesday, May 17; Sunshine Theater (All Ages): Music lovers pay attention to dynasties. This isn't always a healthy habit (cough, Lisa Marie Presley, cough), but if music children can make credible stuff, fans usually pay attention long enough to figure it out. Arlo Guthrie didn't have to be as good as Woody—who could be?—but when he brought "Alice's Restaurant," he showed fans that their natural curiosity with an icon's offspring can pay off nicely. To speak of musical dynasties without mentioning the Marley Family would be like speaking of acting dynasties without saying "Sheen." Out of Jah knows how many Marley children, seven make music, and not one is resigned to ragamuffin torch bearing. They start young, too. Stephen, one of three Marleys representing the Melody Makers, started performing at 6 years old. Skeptical? Good. This Friday, two Marleys will make their second visit to the Duke City in the space of a year. I'm sure they'll be happy to shatter your doubts. Damian "Junior Gong" Marley, the family's youngest at 26, and Stephen, who made his solo debut last month with "GOT MUSIC?," hit the Journal Pavilion last August with Ziggy, Julian and Ky-Mani. This time it's "Welcome to Jamrock," a tour taking its name from a song of Damian's that is already generating good vibes on dancehall dance floors. Way to go, Jr. If you'd like to catch a fire to push you through the workweek this Tuesday, stop by the Sunshine Theater and have a listen.
