Craig Richardson sends me this story with some interesting numbers.
Los Lobos and George Clinton and Bone Thugs and Harmony and Toots and the Maytals charge in the 20-35k range for appearances; that’s not so much considering what you get. Fountains of Wayne (remember them?) goes for 20-30k.
De la Soul goes for 15-20k, as do the Indigo Girls, and for Jefferson Starship it may go up to 25k. The English Beat and PM Dawn (still underrated, apparently) cost only 5-10k.
Bruce Springsteen is a million dollars and up. Many artists I have never heard of go for 200k and up.
Dave Matthews tribute band is 10k, while Dave Matthews is $1 million.
