Charmian’s Circle will present a special concert by the Valley of the Moon Music Festival at the House of Happy Walls Museum at Jack London State Historic Park on Thursday, April 30.

The program will feature works by Antonín Dvořák (1841-1904), performed by Valley of the Moon Music Festival Directors and Founders. Playing London’s piano will be pianist Eric Zivian, alongside critically acclaimed violinist Tien-Hsin Cindy Wu and cellist Tanya Tomkins.

“Jack and Charmian London loved to entertain and Charmian, a trained pianist, would often play her Steinway piano for guests. Is it possible that she might have played Dvorak’s music in the House of Happy Walls?” said Barbara Morrison, a member of Charmian’s Circle.

The concert will offer audiences an intimate preview of the Valley of the Moon Music Festival’s 2026 summer season, which is scheduled to take place in Sonoma from July 11-26.

Each summer, the festival brings world-renowned artists and emerging musicians to Sonoma for performances and training programs.

Charmian’s Circle raises funds to support educational programs, honoring Charmian London’s legacy by expanding and enhancing opportunities for the children of Sonoma Valley and beyond. All proceeds from the April 30 concert will benefit educational programs offered at the State Historic Park.

The event begins with a wine reception at 5 p.m., followed by the concert at 5:30-6:30 p.m. A limited number of tickets — priced at $125 each — can be purchased at Jack London State Historic Park’s website.
