FYF Fest took place in Los Angeles this weekend with headline performances from Kendrick Lamar and LCD Soundsystem. On Sunday, August 28, Dev Hynes took to the stage for a guest filled Blood Orange set. During the show Nelly Furtado, Carly Rae Jepsen, and Sky Ferreira came out to play with the band. Ferreira took the stage to a piano version of her Dev Hynes-produced 2013 single "Everything Is Embarrassing," and then Ferreira provided vocals on Cupid Deluxe track “You’re Not Good Enough.” Furtado, meanwhile, got a huge cheer as she was introduced before "Hadron Collider." Check out footage from all three performances below.
