This one is very nice ideed - in general, I prefer Braxton in duo/trio settings, solo also (don't care too much for his quartet (any quartet) or larger group performances - they are too cluttered and dense, IMO) and in more blowing (as opposed to "composed") mood.
Thus, the discs that Gary listed are among my favorite Braxton works.
Interesting points.
Maybe that's why it took me so long to get into his work with Marilyn Crispell, I love it, but it's pretty dense material.
