Huh, Bennie M.?
Gave the compilation a first listen and enjoyed it as a whole ... thanks for inviting me over
Seriously now, this is hilarious, if just because of the timing! I bought the CD from F. Arbenz and just received it a few days ago - about the same time I finally dl-ed your BFT! (I hope placing a link is ok!). Started buying some of Arbenz' recent/new productions during the pandemic and eventually asked him what old(er) ones he still had, so he dug up one of this for me - beautiful package, edition of 500, numbered ... and a great piano player, too!
Kairos is what they call this, right?
Now I'd love to pin down the twin-singers on #4 but my first thoughts proved wrong (I think), but I didn't find the time to really search yet.
