Andris Nelsons has garnered a lot of attention during his first season as Music Director of the Boston Symphony Orchestra—much coverage in the local and even national press; receptions for the public and an exhibition with a talking hologram at Symphony Hall; placards on buses around Boston and in the subway. He threw out a ball for the Boston Red Sox at Fenway Park. The BSO organization wants him talked about by the man and woman on the street—especially the younger set. It remains to be seen whether a new younger audience will be drawn to the BSO. Eventually, it’s the music that will matter, not publicity.
