I don't know how long this site will be active, but the Boston Symphony has posted a series of
broadcast recordings from Tanglewood. One bit of essential listening (week 8, selection number 6) , from August 18, 1990, is Leonard Bernstein's penultimate performance a mere
57 days before his death, of Aaron Copland's Symphony No. 3. Copland would die on December 2.
The Sunday afternoon BSO concert would be his last. It was released by Deutsche Grammophon with great and somber fanfare, and it's, you know, good and all, but this performance from Saturday night should be the bang he's remembered for going out with. It was quite well regarded at the time.
