Rok, in order to understand that music, you have to first go to the "Misty mid region of wier", then it will all come clear; that's where the picture on the album cover is. Since the jazz as in Nica's book is right down here on the ground, there is no way the two can connect.
You couldn't get into his music because you didn't have an adequate mode of transportation to get to the "Misty mid region of Wier"; if you understand what I just said, you might be able to understand Jean Luc ponty's music.
Enjoy the music.
