I will assume that instead of songs, albums/artists are acceptable?
Brad Mehldau is really, really great pianist. In particular:
Live in Tokyo (solo album)
Introducing Brad Mehldau (first album as band leader)
Art of the Trio (volumes 2 and 5 are my favorites).
He started as a sideman with saxophonist Josh Redman, whose playing I also like a lot. Check out:
Mood Swing
Timeless Tales (for Changing Times)
Freedom in the Groove
Other favorites (just artists now)
Keith Jarrett (piano)
Herbie Hancock (piano)
Roy Hargrove (trumpet)
Nicholas Payton (trumpet)
If you are into straight-ahead jazz, and want to sample a variety of artists, check out Ray Brown’s series of albums “Some of my best friends are . . .” Ray Brown was a legendary bassist, and recorded these albums which featured him along with a variety of other artists who all played the same instrument. I really enjoy “Some of my best friends are . . . The Trumpet Players”.
Good luck listening!
