Reggae artist Luckie D, whose current single, "I'm Missing You Like Crazy," is a radio hit here, is among the headliners slated for today's Jammin' Hawaiians show at the Waikiki Shell. Altogether, more than 17 local bands and singers — including Fiji, Beach 5, Ekolu, Justice Moon, O-shen, above, and Kawao — will perform at the show, set to get under way at 5 p.m. Shell doors open at 2 p.m. Tickets: $18 to $35, with a portion of the proceeds going to support Musical Youth of Hawaii, an after-school program that teaches teenagers the ins and outs of deejaying.
