What else sounds like Albert Ayler's "For John Coltrane"

The only free/avant-garde jazz album I own (outside of almost every Miles album from Miles Smiles to On the Corner, which isn't really the same thing, I think) is Albert Ayler's Live in Greenwich Village: The Complete Impulse Recordings. I bought it a couple of months ago during the Holy Ghost box set frenzy to see what all the commotion was about. I really hated it, mainly because the first track, "Holy Ghost" is so damn dense. Then two nights ago I put on the second disc and had one of those rare, wonderful i-should-sell-everything-i-own-and-live-in-a-mud-hut-and-listen-to-this-album moments and almost bought the box set on-line. Luckily, I didn't (i'm poor, you see) and the mania has subsided a little (although i still think a "SKRONK" tattoo would be cool).

What else is out there like this, specifically tracks that sound like "For John Coltrane" and "Change Has Come." The bopping skronk Ayler is great, but what really touched me are those two tracks. I'm planning to buy Spiritual Unity and Sanders' Black Unity as soon as possible, but then what? My favorite Miles albums are Tribute to Jack Johnson and In a Silent Way if that helps-- mournful/plaintive is good. I guess I like strings a lot, too.

I read through a lot of old threads on free jazz and did a little research on Ascension-era Coltrane, Freddie Hubbard, Julius Hemphill, Coleman, Sun Ra, etc., but they're discographies are huge and the 30-second amazon samples aren't too helpful... Sorry this is so jumbled. Thanks.
