Possibly the first major music festival to do so, Camp Bisco Eleven is now an age restricted event.

Posted today on the event’s Facebook page, organizers announced that you must be 16 or older to attendView the screenshot and read the full post below.

Making this change after tickets have been on sale is a really strange twist in policy and has us wondering what instigates this. Why did they settle on age 16? Why not 18? Why not 12? We have reached out to our contact at the festival and will update this article if we learn any more developments. To be clear, we here at TreeThugger think that his is a smart move- we are just curious as to what brings it about.

If you have purchased tickets and will be under the age of 16 on the start date of the event (July 12th), you can request a refund by contacting [email protected], no later than Friday, April 6th 2012.

Taking place from July 12th – 14th, this year’s Camp Bisco has EDM superstars Bassnectar and Skrillex at the top of the lineup along with festival hosts, The Disco Biscuits. See the full lineup here.

Tickets for the event are on sale now at campbisco.net Tickets start at $170 for a 3-Day Pass. A portion of all ticket sales are donated to the non-proft organization, Headcount, which is co-chaired by Bisco frontman Marc Brownstein.
