So, the album I'm knee-deep in lately and can't (nor want to) get out of:
This is just pure improvisational beauty. I can't get enough of this. It's like a thirst that can only be quenched by one drink -- this album. Sax and drums. Of all of Coltrane's recordings from his "free" period, this and Ascension are my favorites.
Elvin is by far the bigger influence in my own playing, but what Rashied Ali did with Trane is quite brilliant.
