Major Lazer, DJ Snake, & 's "Lean On" is easily one of the biggest songs of the summer so far, and they performed the track this week on "The Tonight Show with Jimmy Fallon."

The guys and MØ took the stage -- but not as DJs behind a booth -- as a live band. And it sounded AWESOME. While MØ sang, the guys played the keyboard, bass, and more, as a group of dancers did their thing on a stage behind them.
