This weekend at Los Angeles’s FYF Fest, Flume‘s set was met with an unexpected visitor. While playing his explosive remix of her “Tennis Courts” track, Lorde made an impromptu appearance onstage to the surprise of even Flume himself. The two joined forces and danced the song away in front of FYF’s main stage crowd.

i had never seen harley play live before so i went down to fyf tonight to watch his set, and basically he played his awesome tennis court remix and i kinda got peer pressured into sneaking up onstage and surprising him for a dance party in front of 20,000 people lol. he had no idea it was happening, i decided to go up literally 20 seconds before i did. and it was FUN being onstage at a festival again having a silly dance!! here’s to cool friends and funny surprises. luv u harley

Watch the fun below, and cross your fingers that this hype will be enough to send them back into the studio. It’s been far too long.
