Why would losing the ability to play together cause the kick and bass to line up? This is the most forced claudism I've seen in a long time.
Because if they lost the ability to play together, then they would be forced to either overdub tracks played individually with a click track, OR use midi, in both of which cases the kick and bass typically lines up.
So what this say, is we get this exact "perfect line up" now, but not because musicians lost the ability to play together and sound naturally, but because we prefer these other two production techniques and audio processing that removes all natural nuance.
Real musicians playing together will result in the kick and bass not being perfectly aligned. If you can't play with another musician properly then two separate tracks will be perfectly aligned in post production. Is the argument being made.
I can only make sense of it as "musicians are so bad at playing together that we don't try". If say the bass player cannot play with others I'm going to record them playing each chord/note in isolation, and then use that as midi samples to track. Do that to everything and you get perfectly lined up music. If you can play together "good enough" then I'm not going to do that.
again these are not exclusive, Even though I fucking hate it, I can drum live to a click track. I hate it because everytime I am slightly off I can fucking hear it like being hit over the head with a frying pan.
