They have shown up on a number of budget labels under a number of different names.  I've heard many of them, have held onto a few, they are pretty routine affairs for the names involved, nothing revelatory or near to the standards of the artists' best or most meaningful work.  But nothing wrong with them, either.  Hampton actually does play on many of them.

Neither one. I'll have to explore those, and I can certainly understand having a bit of difficulty with Lanthimos films.  I liked "Poor Things" and "Bugonia," "The Lobster" and "Kinds of Kindness" less, but like him or not, he certainly makes interesting and original movies.  

Well, a major reason I'm interested is that I have not heard most of them. It may indeed be that they're not all that impressive, though, given the people who recorded for the label, it sure seems to me like there must be some good stuff there. As for "Lionel Hampton presents," that's just marketing. Hampton was--or maybe imagined he was-- a very big name, and while Mulligan certainly was a giant of the music, if one was trying to appeal to a more general public, it's possible that putting Hampton's name on the record might--I repeat, *might*--sell a few more records. I'd just like to hear them all in Mosaic order!  

The fade Beta released some demo's and it sounds promising.  https://www.youtube.com/watch?v=NjxuL3y2c6w  

I read that as well. I guess it can sound like a Monk/Clark mix (though I couldn't spontaneously identify it as a Monk nor a Clark tune 🤷‍♂️).  Either way, one of my favorite Blue Notes. Great band!   Now sampling:
