Pianissimo I’ll mention a few of my favorites.
Maiden Voyage is innovative in that it’s entirely based on suspended chords which is a break from the functional types of progressions up to that moment or the modal jazz. It’s been cited as an inspiration to a lot of modern jazz composers for this use of chords for color (which is not a new concept in music and has been used in classical music for quite some time but maybe not so much in jazz). I guess it will sound like a fairly typical jazz to our ears now but it’s one of the trend setter records in the 1960-s.

The entire album has often been mentioned as one of the pioneering records of the Post-Bop jazz.
And then his famous funky Chameleon track with that iconic Rhodes solo. Almost nobody at the time approached the Rhodes piano in such a manner that’s very different than acoustic piano. I’d go even farther to say he invented the jazz funk type of Rhodes soloing with the Head Hunters 😀

Again, he was able to successfully mix jazz in different trendy styles such as disco, electro-pop, pop, fusion, hip-hop, EDM, etc. and that’s a rare thing among jazz players who often stayed within a certain genre their entire life. He was like Miles Davis in that regard but he’s a keyboard player and utilized modern (keyboard) technology, so naturally he appeals to us keyboardists.
