Did you know that the iconic theme for Peanuts cartoons is jazz? Yes, renowned jazz pianist Vince Guaraldi composed it. At Good Grief! A Tribute to Guaraldi, Schulz, and Peanuts, Sacramento pianist Jim Martinez and his ensemble will pay tribute to the artist, reimagining his work so that it is accessible to a family audience. Hosted by Healdsburg Jazz artistic director Marcus Shelby, the concert will be held on September 24, noon–1 p.m., at the Charles M. Schulz Museum in Santa Rosa. It’s free with museum admission.
