July 27. The weekend begins with the Friday evening concert at 8:30. The BSO website only tells us what is on the program and links the program notes. But if you put your cursor on a picture, a pop-up box identifies the artist; and if you click on the picture, you get the artist's bio. It turns out the conductor is Marcelo Lehninger, and the pianist is Nelson Freire.

Ron Della Chiesa's "pre-game show" begins a half hour before each concert, and for the hour before that they give something called "Tanglewood Today" with recordings that somehow relate to Tanglewood. As always, the webstream is at http://www.wgbh.org/995/ and the broadcasts on 99.5 FM.
