LOL Prince concerts are the only ones I attended in the last 30 years. I've never been to a Michael Jackson one. Back in the late '50s and early '60s I saw several jazz artists performing at small night club venues and quite a few of them at a Playboy Magazine jazz fest.
Charlie Parker
Miles Davis
Dave Brubeck
Max Roach
Sarah Vaughn
Ella Fitzgerald
