Under Appreciated Jazz Piano Players

Jacky Terrasson. His collaboration with Cassandra Wilson (Rendezvous) is very nice, as are his solo efforts.

UNDER appreciated...right?
Dorothy Donegan - One of the few contemporaries of Tatum that had comparable chops...really! She was also a fantastic entertainer with an extraordinary ability to mimic jazz vocalists of various eras. Check out any of her concert recordings and make sure your mouth is taped shut.
Phineas Newborn - Nobody, NOBODY has ever eclipsed Mr. Newborn's pianism. Speed, articulation, phrasing, swing are all non pareil. Criminally underappreciated.
BTW: Thelonious labored in relative obscurity until he was 40 years old because listeners weren't prepared for him. His musical contemporaries knew he was their Mozart...or Beethoven, but it took Jazz fans a long time to catch up. We're still catching up!

Kirk Lightsley (sp?)

Peter Martin, Marcin Wasalewski, Frank Kimbrough, Frank Hewitt

Second the mention by Sdcampbell of Gene Harris,and my other favorites Jr. Mance,Oscar Peterson,Benny Green.Gene Harris is not only not dead however,but (I found out about it too late to attend)the Gene Harris Jazz Festival is April 4-7 in Boise Idaho.Hope there is another next year!Also if anyone is interested,cduniverse has a box set of Errol Garner on Telarc.Some sound better than others,but all are at least decent.
