The Winter Jam Tour Spectacular has had some incredible moments this year, but none perhaps was as incredible for rock band Thousand Foot Krutch as Sunday night's set, which featured a perhaps-unexpected superstar guest.
Country superstar and American Idol winner Carrie Underwood took the stage with the band at the BOK Centre in Tulsa, Oklahoma on March 9, lending her pipes to the hard-hitting song, "Let the Sparks Fly."
"So fun to RAWK it with my pal @carrieunderwood tonight," Tweeted Thousand Foot Krutch frontman Trevor McNevan. "She was born to ROCK!"
Underwood, who was raised Baptist and identifies as a Christian, long has expressed her love for TFK, having included the band's album Welcome to the Masquerade in her iTunes Celebrity Playlist back as early as 2009.
"I love love love this band," she said for the iTunes feature. "They can do it all! Awesome. Trevor has amazing vocals paired with GIANT guitars. Makes me jump around the room!"
After the Winter Jam appearance, Underwood tweeted her excitement for the opportunity: "Just got to rock the stage with @OfficialTFK in Tulsa! So much fun! Thanks, guys for letting me crash your party!"
Underwood is hardly the first guest to show up at Winter Jam. In Atlanta, Guinness World Record-holding high wire artist Nik Wallenda successfully walked a tightrope across the Georgia Dome, while Duck Dynasty’s Reed Robertson, GRAMMY®-nominated multi-Dove Award winner David Crowder and University of Georgia head football coach Mark Richt made special appearances.
