“We’ve done everything in our town before at least a thousand times / If you don’t like wine, you will get bored and lost amongst the vines.” That’s right, folks—the best song about how there’s nothing to do for kids in Napa is “N.A.P.A.” by Defying Truth. But does that make them the hands-down best band in Napa? That’s for the Napa Valley Battle of the Bands to decide. Sponsored by Wandering Rose, the event sold out last year in a stunning, unprecedented support for a local music scene. Last year’s champs Body or Brain play a victory-lap set while contenders Alta Frights, Serf & James, Ove the Garden, In the Know, the Subtones and Defying Truth duke it out for top honors on Saturday, Aug. 7, at the Napa Valley Opera House. 1030 Main St., Napa. 7pm. $10–$12. 707.226.7372.
