This Valentine’s weekend, fall in love with the intensity and driving pulse of Brahms’ last symphony, an exhilarating bouquet of heart-on-sleeve melodies and relentless passion. Violin virtuoso Gil Shaham brings his signature joy and pitch-perfect technique to Dvořák’s Violin Concerto, filled with rich folk-like energy born out of the traditions of the composer’s homeland, and conductor John Storgårds returns, starting the program with the CSO premiere of music by Victoria Polevá.
