I'll save you all from my regular delusions and try to come up with some actually feasible wishes.
Junior Boys - To my best knowledge, they've never played Sasquatch, and haven't played many festivals at all since their new album came out last year. These guys make the ultimate sexytime bedroom dance music, and would make for a really kickass sunset artist on the Bigfoot stage, ala Yeasayer in 2011.
Armin van Buuren - Sasquatch has done a fine job breaking into the electronic genre, but they have yet to get a quality trance artist. Armin put on a mindblowing set at Freaknight, and would make for a really awesome late night set or dance tent closer. Since his price tag might be a little steep, someone like Paul van Dyk or Paul Oakenfold would also be a great snag.
Death Grips - Because fucking Death Grips.
Old Crow Medicine Show - Amazing bluegrass group that would have the entire hill dancing. They have a new album out this year and would probably draw a lot of Mumford & Sons fans in to see what real modern bluegrass is all about.
Ok I want to go watch the Walking Dead now. I'll post more later.
