Jazz covers such a wide area when it comes to music......
One of my GO TO sites for listening to music is YOU TUBE.
I simply typed in JAZZ to the search and this video was one of the first that popped up
Herbie Hancock ... he plays piano and is widely acclaimed for his skills
http://www.youtube.com/watch?v=XrgP1u5YWEg HH is jazz fusion and some of it is pretty technically advanced.... but listen to the colors in the chords..... listen to the chord changes. Not your typical 1-4-5 stuff but still based on it.
You could spend every day for the next 10 years just listening to all the stuff in the jazz world on YT...
Find a player you like and study their styling a bit. The goal is not to get it all in one week but to add new things you pick up from others over time.
