Last night, Dev Hynes opened for Julian Casablancas + The Voidz at New York’s Hammerstein Ballroom. The two have been working together quite a bit recently: Hynes also did a Blood Orange set at the Tyranny album release show at Shea Stadium and they had a long talk with each other on Hynes’ radio show a few months back. During last night’s concert, Hynes came out on stage during the Voidz set and performed the Strokes’ track “You Only Live Once” with the band. Watch video of that below.

This is what Hynes tweeted after the show:

Tonight I got to sing with a hero onstage in the city I love on a day I woke up alive and well. This is luck. It's all luck.

Casablancas has also been vocal about his appreciation for Hynes’ work. In a recent interview with We All Want Someone, the singer said that his recent Jimmy Kimmel performance “solidified him as the baddest musician on the planet for me. He’s a special, special being.” Casablancas also mentions in the same interview that a video for the Voidz track “Human Sadness” will be coming before Christmas, so you can look forward to that.
