So many good choices as to be expected, there have been many talented pianist over the years and then factor in the multitude of styles.
I'll base mine on who I find myself listening to the most often.
Theloneous Monk, Herbie Hancock, Kenny Barron, Tommy Flanagan and the sleeper on my list Barry Harris (a pure bopper with a beautiful left hand).
I could name many more, I 'm just glad someone recorded these fabulous musicians.
