The MSO welcomes Eric Jacobson, “an interpretive dynamo” (The New York Times) to conduct Dvorák’s Seventh Symphony, a work of tragic grandeur flecked with sunlight. MSO Principal Tuba Robyn Black takes center stage for Vaughan Williams’s Tuba Concerto, which begins with a brisk march, ends with an energetic flurry of sound, and showcases the unique qualities of the instrument throughout. This dynamic program opens with Tchaikovsky’s delightful Serenade for Strings, featuring a memorable waltz and spirited Russian folk tunes.
