Stanley Clarke and George Duke headline the Saturday show. Brian Culbertson does the same on Sunday. But come early for the bands and performers you might not know—that’s a big part of the pleasure of music festivals. Some fast fest facts that might be helpful: Children under 12 are free. There’s a free shuttle from Glendale center. Umbrellas aren’t allowed (you wouldn’t want to annoy those behind you, would you?). And the food vendors are cash only. Details here.
