Oklahoma duo, The Swon Brothers, got the party started right opening up for Carrie Underwood at 'The Storyteller Tour' at the Casper Events Center.

You may recall The Swon Brothers from the the fourth season of NBC's 'The Voice'. The group finished in third place. It is very fitting that these guys opened up for Carrie Underwood, who knows all about TV singing competitions. I bet this is not the last Casper will see of this energetic group.
