Rab, it's only the first two of Blythe's Columbia albums -- Lenox Avenue Breakdown and In the Tradition -- that were released in the 70s. All others were in the 80s. So your understanding isn't really off the mark.
I can ask Dan about it. Here's what I know. Along with DeJohnette, Purcell played and recorded with Muhal Richard Abrams, Chico Freeman, David Murray, and others. One that stands out in my mind -- perhaps because it's with a small ensemble, unlike a lot of his other work -- is his sideman appearance on Chico Freeman's Pied Piper (BlackHawk, 1986).

I hope that means "interesting" as in compelling, not "interesting" as in odd.
Not sure whether that's possible. Will look into it.
However, as far as I'm concerned, you can just comment here if that's your preference.
Blythe died in 2017. He was 77. So he didn't really die terribly young. ... But I think your impression that he did is indicative of the fact that Blythe didn't maintain the high profile that he had at the start of his career.
Many of Blythe's post-Columbia recordings are outstanding, IMO. For example, Focus from 2003. But they're far less well-known.
Totally agree.
