I did an informal survey on Craigslist in Boise, Denver and Phoenix asking musicians to respond with information on what the local clubs are paying. I even got a random response from Cincinatti.
I compiled the responses into a pdf file that can be found here.
Please comment on this blog and add more information about the clubs in your area of the Intermountain West. I will update the file as I receive more information. Could be a good comprehensive resource for musicians throughout the area.
