This came out on CD some time ago. I would be surprised if it were not still available, and it should certainly have both versions Coltrane recorded in the studio on that one recording date/day in 1965. Recently a DVD of long lost Coltrane performances on video was released. That includes his famous quartet performing Ascension, the only known live performance. But the quartet version is a different animal from the large ensemble version with five saxes, 2 trumpets, etc. What makes the piece so powerful is the SOUND of the large ensemble.
