The Santa Rosa Symphony historian Kayleen Asbo made a series of videos weeks ago about this season’s concerts, but her comments introducing the shows this weekend are more timely than ever. “This particular program,” she says on YouTube, “is one that explores the power of music to heal and transform. I like to call it the light in the darkness.” Mei Ann Chen conducts Shostakovich’s Festive Overture, a piece with the power to inspire new resolve to those in despair, after the North Bay fires, plus Tchaikovsky’s Piano Concerto No. 1 with soloist Nareh Arghamanyan. The Santa Rosa Symphony is dedicating its season to first responders and those who’ve lost homes in the fires, both groups of which qualify for free tickets for the remainder of the season.
