Lights. Camera. Action. As soon as the sun went down, Los Angeles-based indie-pop band Foster The People took the Which stage at Bonnaroo, not only putting on a killer performance, but also a pretty sweet light show.

The group is well known for their song "Pumped Up Kicks," and had an impressive-sized crowd gathered to watch their evening set. Foster The People closed out the Which Stage on Friday with high energy and a wild dancing crowd.

Singer Mark Foster rocked a white suit that seemed to light up the night. The band performed "Don't Stop (Color on the Walls)," "Houdini," "Miss You," "Call It What You Want" and of course, "Pumped Up Kicks."

The band also had a special guest pop on stage. A sun with a face on it hung above the stage, with a "flame man" popping out to an awed crowd.

Foster The People's performance was live streamed on YouTube Friday night, but if you missed it you can check out the band performing "Don't Stop" right here.
