Kygo and Ellie Goulding teamed up to perform an acoustic version of “First Time,” and it sounds as beautiful as ever!

The two hit up BBC 1 Radio‘s Live Lounge to perform two stripped down tracks: a stunning cover of “Sign Of The Times” by Harry Styles, and their hit song “First Time,” which has racked up nearly 9 million plays on its music video alone (watch). Their song also broke the Billboard Hot 100 and is destined to be one of those we remember when we look back on summer 2017.

During the performance, Kygo demonstrates his ability to perform live and Goulding angelically slays her vocals, per usual. Watch the clips below and check back with BBC Radio 1 to watch the full performance!
