Aug. 19-20: Matriarchs of Music in Cotati

The North Bay’s Cotati Accordion Festival, devoted to the old squeezebox, turns 27 this year and is marking it the “Year of the Woman” to celebrate all the contributions that women have made to the instrument. This year’s honorary director is longtime North Bay musician and instructor Marjorie Konrad, who’s responsible for teaching generations of accordion players. Headlining the fest are other veteran players, like Amy Jo Sawyer and Gail Campanella, and the event boasts international talents along with the local stars. The festival goes all weekend, Saturday and Sunday, Aug. 19–20, at La Plaza Park, Cotati. 9:30am to 8pm both days. $15–$30.
