"Skol," say Duluth bluegrass heroes Trampled by Turtles

Depending on how you ascribe dollar values to Minnesota music faves Trampled by Turtles and Mason Jennings, the $1.1 billion People's Stadium might be starting to prove its worth. 

That's because TbT -- those beloved Duluth bluegrass pickers who just rocked their own Festival Palomino on Saturday -- and Jennings -- the Twin Cities-launched indie-folk star -- will both perform Sunday on opening evening of U.S. Bank Stadium in Minneapolis. 

The two-stage event will go down at The Commons area outside the stadium, with Jennings slated for 3 p.m. and the Turts scheduled for 4:30 p.m. The Vikings and the Packers will then do battle at 7:30 p.m. in the first-ever regular season football game at ... well, whatever you fine folks wanna call our shiny new football palace. Johnny Holm Band is also set to perform. 

Once inside, fans will hear 2007 American Idol champion Jordin Sparks sing the national anthem.
