Sure, you could go to the Wells Fargo Center this week and be swooned off your feet by Englebert Humperdink. You could relive some of the gritty classic rock of the John Fogerty-less Creedence Clearwater Revisited. Or you could not spend a dime and expose yourself to new cultural horizons with the Fiesta Independencia, celebrating Mexico’s bicentennial anniversary, with music by Omar Arreola, Lucy Diaz, Jackie Contreras, Trio Nuevo Amanecer and more. (There’s even a group called El Bohemio de la Banda, which the Bohemian naturally endorses.) Art, ballet folklórico, mariachi and piñatas are all on the menu, and don’t miss the salsa contest. It’s all happening Saturday, Sept. 18, at the Wells Fargo Center. 50 Mark West Springs Road, Santa Rosa. 3-7pm. Free. 707.546.3600.
