Some great records here, I do enjoy these Best Of threads on the Music topic.
Another vote for John Martyn, "Solid Air", the best ever Folk Rock album IMHO. A great artist lost to drink, why are there so many?
I know it's not popular, but why no classical or opera, the latter is my particular vice. Two great, very accessible, lyrical operas
Puccini's La Boheme conducted on Beecham on HMV. When Mimi (Vottoria De Los Angeles) enters to ask for a match in Act 1, you'd think an angel had entered the room.
Verdi's Otello on EMI, conducted by Maazel, with Domingo. Listen for the offstage canon at the beginning, a good test for bass and soundstaging.
