Did you know that outside of tiny bar level gigs nearly all deals for bands to play live involve a split of the actual ticket sales between artist and promoter? Did you know that above the bar level the venues actually handle, and take a substantial percentage of, the merch sales?
And so on. I don't know what it is about music but for some reason there's like a tradition in online forums of people going on and on about the nuances of the financial deals in the music industry by people who have absolutely no idea what they're talking about.
