If you go to the above line that says "Links" you will see the first category being "Festivals". The festival that I work for is the "Branches and Roots Festival" which has this years line up. I started booking musicians the week following last years fest and received about a month ago the last contract. Bios are not listed as yet but will be very soon. We are a small festival in comparison to other ones in Canada, but we are young and growing. I do agree with you in that many festivals do not list to early and I'm not sure as to why not.
Don't know where your inquiring from but if your in the Quebec area around July 28, 29, or 30th. You would be more than welcomed.
