The Boston Symphony Orchestra opened its first concert of the season in a fashion that reflected the all-Russian program: quick and to the point. Upon entering, conductor Andris Nelsons was greeted with a standing ovation; however, the audience barely had time to sit down before the BSO began Shostakovich’s playful Ninth Symphony. It was easy to appreciate the lightness of the strings and winds juxtaposed with the fanfare of the brass. I found myself captivated by Nelsons’ conducting, which conveyed excitement and scrutiny to detail, and the way the orchestra responded in kind. Navigating through Shostakovich’s bright Allegro, his eerie Moderato, and his loud Presto, the musicians demonstrated their versatility in both technical and emotional depth.
