Interesting that this just came up. One of our bands did exactly this at our last show. But for a much cheaper price (i think they charged us 10$) so we still got paid plenty for the show. Got the tracks in email today. Literally 15 different mics from bass, guitar, vox1,vox2, tom1,tom2 etc etc etc, even two ambient crowd recordings if we want to maintain the "Live sound". I'm very happy with the quality of the tracks and look forward to the mixing process. Always fun to hear your isolated bass, really lets you pinpoint things you should work on.
