The principal orchestral concerts of the Symphony's Tanglewood season will begin on July 5, and continue August 25. There will be concerts on Fridays and Saturdays at 8:30 p.m. and on Sundays at 2:30 p.m. — with a different program each time. I expect all of these performances to be broadcast and streamed live over Classical New England.
So for now, you can enjoy some lighter fare, if that's to your taste, and in July and August, it will be a real bonanza of the more usual concert repertoire, with plenty of famous guest artists. Some pieces that were played during the winter season find their way into the schedule for Tanglewood as well, but there will also be plenty that wasn't played last winter. The full Tanglewood season brochure is here.
