Proving that it's more than a venue for blue hairs and their grandkids, the Kravis Center for the Performing Arts hosts Sunday's Rock to Rebuild. From 2 to 6 p.m., a handful of the area's top acts takes the stage at the Gosman Amphitheatre. The outdoor show features bands like Truckstop Coffee, Doorway 27, the Olive Tree, the local, and Inhouse; solo musicians Jason Colannino and Brian Franklin; and improv comedy troupe Mod 27.
Meanwhile, the Helping Hand Concert at the Surf Café is definitely about helping; the concert part, well, that's sort of a misnomer. Sure, 20-plus bands perform Friday through Sunday -- Souleye, Blood and Batteries, and JJ Immortal, to name a few. But there's also a blood drive, food and clothing collections, CPR and first-aid clinics, a firefighter boot camp, raffles, games, and -- hang on, we're almost done -- a cook-off contest. Of particular interest is the dunk game, in which random volunteers step inside a dunk tank set up in the parking lot. Five bucks gets you three balls; a direct hit wins you a free beer. Even if your aim sucks and you go broke without a single dunk, just remember: It's your donation that counts. You can try out for the Marlins some other time.
