Rok, people may not believe this, or accept it as truth, but music is a reflection of everything that's going on around the musicians. While this is my perception, I would not debate it with anyone who thought otherwise because it's far too broad.
When I was listening to Roy Eldridge "Little Jazz" on trumpet, I could see men and ladies on a ballroom floor in their best attire, dancing to that kind of music. Although this scene was from a movie, because I was too young to be on any dance floor at that time, I can still visualize it.
I began jazz with Bird, Diz, and Miles, and it's just recently that I'm going back to swing, thanks to you.
Here's something that Acman posted, which is classic jazz in the same vein as what you and Alex posted, but it's relatively new, which means there are musicians still putting out some good "classic jazz".
