August 26. On Sunday afternoon Maestro Frühbeck leads the now-traditional Beethoven Ninth to close the Tanglewood season with a guaranteed "standing O." But there's more: the world premiere of a piece titled "Koussevitsky Said," by John Harbison, for chorus and orchestra, commissioned by the BSO for Tanglewood's 75th anniversary.

The page also tells us what Classical New England will use to fill the BSO concert slots on the three weekends between the end of the Tanglewood Season and the opening night of the Symphony Hall Season.
