Interesting. It sounds good at the start but becomes cacophonous shortly thereafter.

Another war story here: I used to run a 16 track mixing console with a rock band. The guitar player played with 2 different bands. He got a gig in a club one night and both bands showed up. Everybody insisted on playing.

It was OK but the less accomplished drummer insisted on playing a drum solo. I ran his drums through a delay in the range 160 - 200 mSec and mixed it back in. Every drum strike was doubled and the audience liked it. I don't think they would have been as enthusiastic if they had heard what he was actually playing.

How much did you listen to? The cacophony comes in waves, and these waves become the sound itself.

It's a technique that goes back to Steve Reich in the 1960's. One day I'd like to see some of this stuff lip-synched to the appropriate visual:
