What happened to Dev Hynes and Samantha Urbani earlier this month is awful and terrifying, but that didn’t stop Blood Orange from delivering a colossal set at FYF. Starting five minutes early — without even a band — Hynes ran out (still with his leg brace on) and started singing a cappella, as everyone else in his band set up and slid right into place. Not a second was wasted, but it was all performed with a laid-back ease. Hynes gave everything you could have wanted, throwing in a new angle with each song: blistering guitar solos, impeccable dance moves, choreographed backup dancers, a lovely duet with Urbani, a guest spot from collaborator Kindness. It represented the best of what a music festival should be: strikingly modern, yet part of a grand tradition, and for a brief period he made you forget there was any other band there.
