tUnE-yArDs hit the stage on The Tonight Show starring Jimmy Fallon to perform "Water Fountain" from their Nikki Nack LP with a bit of help from The Roots. The super fun performance - a live rendition of the video for the track - is executed against a backdrop of dope visuals that, combined with a few awesome props, feels like an homage to the whimsical set of Pee-Wee's Playhouse. The Roots file onto the stage with instruments that brighten up the sound while adding to the percussive weight of the performance. Check the footage below to watch tUnE-yArDs' performance of "Water Fountain." Pre-order the Nikki Nack LP via iTunes. Stay tuned for more from The Tonight Show starring Jimmy Fallon.
