Reunited rockers Fall Out Boy stunned fans attending California's Coachella festival on Saturday (20Apr13) after joining rapper 2 Chainz onstage for a surprise appearance.
The unlikely acts came together on the second weekend of the popular three-day event to perform the remix to the band's new track, My Songs Know What You Did in the Dark (Light Em Up), with 2 Chainz sharing the microphone with frontman Patrick Stump and even picking up a guitar to strum alongside Joe Trohman.
Introducing the punk stars to the spotlight, the rapper told the crowd, "Not only did I come to save hip-hop, I came to save rock and roll", making a reference to the group's comeback release Save Rock and Roll.
Taking to Twitter.com after the show, Fall Out Boy bassist Pete Wentz wrote, "Thanks 2chainz (sic) for having us out at coachella..."
The hip-hop star later kept himself busy by teaming up with producer Diplo to hit the stage during his Major Lazer set, when he rapped along to the track Bubble Butt.
