Yonder Mountain String Band performs at Red Rocks in Morrison, Colo. last year.

Official artist announcements for the 2011 Harvest Music Festival won’t come until June, but if you believe what you read on the internets, you can get at least some idea of what to expect on Mulberry Mountain this fall.

A handful of artists, including Yonder Mountain String Band, Reckless Kelly, The Reverend Peyton’s Big Damn Band, Emmitt Nershi Band, Oakhurst, Peter Rowan and That 1 Guy are listed to appear at the festival on the popular concert tracking website, Pollstar.

None of that is official, of course, but Pollstar has a pretty good track record of being correct on this type of thing.

The festival will be expanded to a four-day event this year, and organizers say they are capping attendance at 7,500 people.

Festival dates are Oct. 13-16, and tickets went on sale April 22. Four-day passes are $99 (price includes camping), and a Saturday-only day pass is $74.

Here are the early, unofficial bands that Pollstar indicates will be playing the festival this year.
