I came across this video of Avantgarde German composer Karlheinz Stockhausen's String Quartet where musicians play while sitting in 4 hovening helicopters.
On top of that listeners in the concert hall could hear and see through radio and TV livestream.
How crazy is that?
Let me know what you think.
Thanks, @organduo, for your support
You are right. This is crazy... What's next: an opera in a swimming pool?
