With Ahmad Jamal, you can decide which aspect of his piano you like best; light and whimsical, or really banging, and go with that.
Right now I'm listening to "Poinciana", from the album "Freeflight", and it's interestingly different; so different, that I will get that CD if it's available.

The way Ahmad gets so much out of the same tune, reminds me of "homeboy" Eddie Fisher, and the way he got so much out of "The Third Cup". I went to see him live every time he appeared at a place called "Mothers". He could work that jam around so many different ways, that you could listen to that one tune all night.

Enjoy the music.
