WHAT IS THE MOST UNIQUE SONG THAT YOU HAVE EVER HEARD?

There's also a piece where Beethoven's Moonlight Sonata was sent in the form of sound waves to the moon, it reflected off the moon and then was recorded and played back once it arrived here back on Earth.

I'd recommend hearing the Charles Dodge piece 'Any Resemblance is Purely Coincidental'

I'd recommend seeing Eighth Blackbird.

WDR 3 radio in Köln would play works created by various tape loops, that were super imposed and interwoven with original compositions. I loved these pieces and am unsure whether or not they were all constructed by the same person/s. It's unlikely but if anyone else knows about these works, I'd greatly appreciate some info.
 
The most original performance experience I ever had was seeing Moritz Eggert play a film score ( piano, cap gun, etc...) while showing a German Noir Silent film.

peterr991, Thanks for the link. It’s referred to as Schlager.
