You don’t have to be a polka fanatic to love the Cotati Accordion Festival. The musical extravaganza turns 26 this year and presents a weekend’s worth of musicians from all walks of life sharing in the joy of the accordion. This year’s honorary director is Lou Jacklich, who’s spent a lifetime squeezing and strutting around the Bay Area. Artists lined up for the fest include Chinese sensation Jianan Tian, Finnish wonder Viivi Maria Saarenkylä and local favorites like the Vivants, Haute Flash Quartet and many others. Last year, the festival raised over $23,000 for local nonprofit groups, and this year they’re aiming even higher. Get your polka on Saturday and Sunday, Aug. 20–21, at La Plaza Park, Old Redwood Highway, Cotati. 9:30am–8pm both days. $19–$29. 707.664.0444.
