What the heck are “angular eccentricities?”
I also really liked "East/West" by the Paul Butterfield Blues Band. Although mostly a blues band, The 13-minute instrumental track "East-West" incorporates Indian raga influences and some of the earliest jazz-fusion and blues rock excursions, with extended solos by Butterfield and guitarists Mike Bloomfield and Elvin Bishop. It's other worldly.
I can't stand what I call progressive jazz because it has no melody nor resolution. I may not have the ear or feelings for notes that just go everywhere. I prefer flow in my music.
