Its bold colors and tropical flowers have been collecting dust in the closet for years. But now that Hawaiian shirt has a place to party—the Benefit Concert & Luau. Featuring live music from Maui band Jason Arcilla & the Rhythm Sons, the luau will serve a Hawaiian-style smoked pig. And, yes, Hawaiian attire is encouraged. The event, which will benefit the Gladiators K–8 wrestling program, will be held on July 9 at 5 p.m.at Cache Creek Vineyards and Winery in Clearlake Oaks. Tickets are $75, or $25–$35 for the concert only, and can be purchased at cachecreekvineyards.com/events.
