How much are 'famous' musicians actually making?

When I mean famous, im not talking about Justin Bieber, Beyonce or TayTay since theyre are leagues beyond everyone else in revenue. Im talking about a mid tier 'famous' band like lets say Pale Waves or American Football, bands famous in their own niche but not at the level of superstars.

My educated guess is that they make something 50-90k a year, and thats after the managers, promoters, producers, record label gets their cut, and it may or may not be after taxes.

Honestly no idea, but if someone could give their insight, I would really appreciate
