That is a tough request. I think I would choose the three below, not so much because they are the best, but because they cover a range of styles: Miles Davis In a Silent Way-esque musings, up-beat piano jazz, and reflective ethereal playing respectively.
1. Lars Danielsson - Melange Bleu
2. Neil Cowley Trio - Loud..Louder...Stop! (spelled incorrectly the first time)
3. Helge Lien Trio - Hello Troll
The entire list is good, and I find there is above average craft evident in the production values. Go on iTunes and you can hear samples of all.
