Nice one. Yes, I have it and was equally pleased when I bought mine. Haven't listened to it for a while but shall dig it out
Whilst talking about Tchicai, have you got this one @Pim? Not to be missed
https://www.discogs.com/release/4984604-John-Tchicai-Charlie-Kohlhase-Garrison-Fewell-Cecil-McBee-Billy-Hart-Tribal-Ghost
His most recent release
https://www.discogs.com/master/3409174-John-Blum-David-Murray-Chad-Taylor-The-Recursive-Tree
His Discogs shows at least 4 releases since 2020. Definitely still active
The Astral Spirits is not a subset. Different concert, from Glasgow.
I bought my copy from Seymour Wright in person the other day and had a very pleasant short chat with him. He was very pleased with how both the box set and the AS double LP have come out.
I haven't listened to the LP release yet.
