Hi all,
This will date me, but I don't care. I've lived through some wonderful decades and eras of music.
In no particular order and mixing genres:
1. Chuck Berry
2. Little Richard, the Dell Vikings
3. Buddy Holly, Jerry Lee Lewis
4. Janis Joplin and Joe Cocker (together in concert!)
5. Lambert, Hendricks and Ross (great jazz vocal trio)
6. Ray Charles
7. Gospel at Colonus (black gospel musical version of Sophocles' tragedy with Clarence Fountain and the Blind Boys of Alabama)
8. Oscar Peterson
9. Pete Seeger and The Weavers
10. Il Trittico and Tales of Hoffman at the New York Metropolitan Opera
Runners up: Joni Mitchell at a small club in Toronto (The Riverboat) before she became famous in the US.
John Rutter Requiem at Carnegie Hall. Several great folk acts, Ian and Sylvia, The Tarriers, Jim Kweskin Jug Band; Ronnie Hawkins and the Hawks (before they became The Band, backing up Dylan); Levon Helm (Midnight Ramble at his Woodstock studio).
Lots of other great ones.
Alan
