All new to me.
On the timestamp piece,"Część 2," it appears that some players (pianist) have some kind of score, possibly. Conducting definitely plays a major role. Also, the use of external material - colored scarves. Does the projected image represent anything? It seems important. Very soundscapey and deeply layered.
Definitely curious to learn what exactly is going on here.
The next piece,"Część 3," is very different with its theatrics. I'm a sucker for such things. I'm not sure if it's a cultural difference, but I'm sensing some humor. Actually, throughout the performance, musically, there are many funny moments.
Plus, anything "anti-elitist" is always welcome!
EDIT: This Ryszard Latecki guy has quite the impressive YT channel!
