Possible book print?

Foques

Hi all.
Got a question for you.

I shoot a lot of shows, and people seem to prefer my style over few other shooters.
What I want to offer our local musicians is to publish a book (clearly, it will be a heck of a project, and i'm thinking about spanning it into a full year).
Basically, next year, around this time, I want to offer local musicians to purchase a book that will have multiple bands' pictures.

I understand that i need a model release for this kind of event.. Question is:
How do I word it?
Should I have bands sign the release every time I shoot a show for next year, or can I just have them sign a release for any future shoot as well? (there are a few bands that I shoot frequently)?
How would you go about doing something like that?

In eras gone by many of the masters used a model release that spanned thru a set of dates.....if they were shooting the same "model" several times a year and knew it...the model release would say for all images taken from date to date.........
