Under Appreciated Jazz Piano Players

Virtually anyone who recorded a solo recital for Concord CDs in the Maybeck Recital series. Largely terrific performances, in splendid sound. Look for all 40-odd of them... many have been remaindered recently. With perhaps one exception, all of them are highly enjoyable-- both those by pianist with whom I was previously familiar and by several who were new to me.

Hey, what about Oscar Peterson and Andre Previn?

Duke Ellington's mastery of the piano is not always given its due. Likewise, Fats Waller is sometimes seen as an entertainer and his musicianship is not fully appreciated. Not always easy to say when someone is under appreciated. Presumably, you have to discount the fact you are talking about an under appreciated art form. Some were appreciated by critics yet did not sell a lot of records (or vice versa). Some were appreciated in their time but are under appreciated today (or vice versa). At any rate, other jazz pianists who in some sense were/are under appreciated include:
Al Haig
Tommy Flanagan
George Wallington
Mary Lou Williams
Martial Solal (his At Newport '63 LP is a gem)
Michel Camilo
Monty Alexander
John Campbell

In response to 4yanx–I think you can't go wrong with Montreux '77 and Alone with the Blues, but Ray Bryant is pretty consistent in quality, if quite eclectic in material.

Also, Tommy Flanagan is so masterful that I forget that he may be underappreciated. Giant Steps, his homage to Coltrane, is one of my favorite albums of any type.
