“Established bands” would be the exception these days. There are a handful of bands that are even capable of generating enough sales to fill an arena without 4 other acts. Huge bands like foo, Metallica, g’n’r, etc play based on guarantees before the tours are even booked. The average band that was formed in the last 20 years is going on a tour playing fairly small venues for next to nothing. They will make most of their money on merch sales. The labels aren’t fronting these guys any money whatsoever and most of your “indie” labels are going belly up. That’s why you see so many bands distributing their own music through their own “labels” which is just a front name for them to use some international distribution company.
That’s what saved labels like road runner. They turned from a label into a distributor.
