This is interesting, thanks. It's clear that the promoters take pretty major risks and can wind up taking a bath if tickets didn't sell. I think you have a very good point about solo acoustic performers. My wife and I just went to see Colin Hay (former Men at Work frontman) play solo in a theater that seats maybe 1500-2000 and seemed fairly full. Tix were maybe $30 each. He joked a lot about how his pop star days were over and he doesn't get hits on the radio any more. But the show was just him with four guitars (he also joked about how he used to have a guy who would tune them for him). So maybe $60,000 was made on the night and he wasn't paying for buses and trucks transporting two dozen roadies and heaps of gear. If he got 10% of that and played 20 dates at that rate, not having to split the 10% with anyone, he's making a cozy six figures. I saw Victor Wooten in the same theater, touring with six people, and the place was not more than half full - I'm sure the whole audience was local musicians. Great show. But $30,000 on the night, assume 10% to the musicians, split six ways, starts to look like a $500 gig. I guess the thing to bear in mind from what you describe paying for acts is that that money goes to the artists' organizations - not all to the musicians themselves.
