Young star Shamir has one of those great, euphoric disco-diva wails, and if dance producers aren’t constantly bothering him for collaborations, they really should be. Last night in London, Shamir took the stage with one of the best things dance music has going right now. The UK pop-house trio Years & Years were playing a show at London’s Brixton Academy, and Shamir came to the stage to help them out on their swooping banger “Real,” sounding as amazing as you’d hope. Watch the performance below.

Shamir’s album Ratchet is out now on XL. Years & Years’ album Communion is out now on Polydor.
