Please help identify - very hard with little clues

So I listened to that song and a few more. Interesting music, will listen more, but not the one I am searching for.

If you took this song, played by a jazz trio, extended to 1 hour with variations on the melodies, which would be a bit more difficult to identify, then you would get an idea how the record I am searching for sounds🙂
 
Yeah, I agree that tune is not the best example of the stuff they usually play. They do have some very nice music though.

I think you're chasing for a specific live performance rather than a long track, and to be able to find that you need to know at the very least the artist/band, perhaps also the year and location to get just the right one.
 
Unfortunately, I know nothing of that🙂 But with the power of Spotify radio I was able to discover some things that are close to what I wanted to find. Maybe one day, I will find it. And I will definitely recognize it when I hear it.
 
I tried to contact the radio, no answer. They definitely have a list even from 20 years ago - 50 records a year would be no problem to go through I have a max 5 year window, could go one by one. They just do not talk to ordinary mortals...
 
It was official Czech Radio - and it was their "Midnight Jazz Hour" broadcasting, where they usually play the whole CD as is. It was definitely a recording from a concert, with applause between songs, but I cannot imagine how they would get that unless it was oficially released long time ago - and on a CD. No silence between tracks as far as I can remember.
 
Just for fun, these are the artists ChatGPT listed, there is a star where I already knew the name or heard a few tunes of before:
*The Bad Plus

*Oscar Peterson Trio
*Ahmad Jamal Trio
*Winton Kelly Trio
Paul Bley Trio
*Esbjorn Svensson Trio

And further recommended that "I might be interested in":
Medeski Martin & Wood
Ron Carter Trio
Tord Gustavsen Trio
*Monty Alexander Trio
*Chick Cora Trio
Jimmy Smith Trio
Marcus Roberts Trio

Maybe any of those would ring a bell for someone?
