Dev Hynes joins Julian Casablancas on-stage to sing The Strokes’ ‘You Only Live Once’

Casablancas' currently touring with new band The Voidz

Julian Casablancas was joined on-stage by Dev Hynes in New York last night (November 25) for a rendition of The Strokes‘ track ‘You Only Live Once’. Click above to watch fan-captured footage.

Casablancas was performing with current band The Voidz at the Hammerstein Ballroom when Hynes, who currently records under the guise Blood Orange, emerged to sing lead vocals on the song, which first appeared on The Strokes’ 2006 album ‘First Impressions of Earth’.

The duo combined ‘You Only Live Once’ with an early demo version of the song titled ‘I’ll Try Anything Once’, which was later released as a B-side to the single ‘Heart In A Cage’.

Hynes had opened for Casablancas earlier in the night and after the show he took to Twitter to voice his delight at the special performance, posting: “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.”

Speaking to NME recently, Casablancas asserted that The Strokes will record new music in 2015 “if the vibe is right.”

Asked what the “vibe” of The Strokes is at the moment, Casablancas replied: “less mystical”. He then added: “I think you have good work chemistry if you are just honest with each other and you just wanna do something good, and you just wanna put in all your magic, and create something cool with other people’s magic, with friends. I think ‘the vibe’ in the recent past was lost, but I think we learned how to work together better. More professionally. But now I think we’re looking to combine those things.”

The Strokes already have one confirmed live date in their calendar for 2015 – a headline set at Spanish festival Primavera.
