The Greeley Stampede in Greeley, Colorado was completely sold out in 2015 — thanks in part to sibling trio the Band Perry, who brought a high-energy set along and some serious dance moves.

Big singles like "Chainsaw," "Better Dig Two" and the very emotional "If I Die Young" were included in the group's set, as was a cover of "Uptown Funk," which had the entirety of the crowd dancing and singing along.

But TBP also got serious with the packed crowd, telling the story of their song "Pioneer." Kimberly Perry said that song was their guiding light for the album of the same name, despite being scared to write it after releasing "If I Die Young." They didn't know if anything could ever top it.

"The days ahead of us are brighter than they have ever been before," the frontwoman told the crowd. She reminded fans that they're working on their next album, which is due out in a month.
