Oh. That does make it a little less cool. But only a little.
25 years ago we were still learning techniques like this in the darkroom. I actually feel like you could edit more back then, in a different way. Mess with chemicals, overlays, timing... You could physically do it, like natural piano/drums dynamics vs digital sounding too clean.
Yeah, I was also surprised when I read about it on Wikipedia.
