I would add Joplin, Gershwin, Segovia, to name a few
Can’t argue with any of those. And for jazz (aside from the already mentioned Ellington, Parker, and Tatum) — Satchmo, Ella, Mingus, Monk, Bean, Wes, Benny G, Louis B.....
Anyway, mentioning all these greats on a Michael Jackson thread seems more than a bit out of place.
Pavarotti.
