Jam and indie rock band, O.A.R. (Of a Revolution) was the headlining act at 'Rock at Park City' last night during the Sundance film festival.

The band opened their set with "This Town" and they even did a brief rift/cover of Outkast’s “Spottieottiedopaliscious.”

The band is currently working on their next album and already have decided on the lead single of "Peace,"Billboard added.

Before the band took the stage last night, they spoke about what it was like to return to the festival after some time apart and time on the road with their "Sounds of Summer" tour. "[It’s like] when you go to your hometown for Thanksgiving and you’re around such familiar faces that you haven’t seen in years, but it just picks up right when you left off. That’s the entire emotion of this album — trying to create and explain that feeling," said Roberge.

Chris Culos, drummer for the band, spoke about what life was like on the road for the band, to My New Orleans magazine.

"We never play the same show twice. Even if you’ve heard the song before, you’re going to get a revamped version of it. For us, it’s fun because it keeps it fresh. For the audience, it gives them a reason to come back year after year," said Culos.

Billboard captured the performances during the festival. Watch "Hey Girl" and "That Was a Crazy Game of Poker."
