BK, I have a memory that you liked Verdi's Otello, his penultimate opera. At the age of 80 or so, he retired from composing with his masterpiece, Falstaff, which has a better script than its source, The Merry Wives of Windsor. I grew up with Bernstein's recording, and I think it's really good. About the same time London-Decca recorded the work with Solti. Both were tie-ins with Zeffirelli's Met production, which was one of the Met's great productions. That was my second Falstaff recording.
I also liked Giulini's later recording very much.
