The BSO has two more concerts on its schedule this weekend, Saturday night and Sunday afternoon, at Tanglewood, its beloved summer home in the Berkshires. The orchestra is set to begin its 146th season in September, with Nelsons and Yo-Yo Ma part of opening night on Thursday, Sept. 17.

I had to look up who Nelsons was and I have to say, I’m a little relieved. Yo-Yo Ma deserves every accolade he gets. www.youtube.com/watch?v=i0QCHdQxqKI&list=RDi0QCHd…
