While Goulding credits UK rapper Tinie Tempah with introducing her to her royal fans, what in the world could have inspired this tribute from a metal band? One Without say it’s down to simple appreciation for a good song.

“We actually heard “Lights” for the first time just a few weeks ago, and were blown away by how good it was!” says guitarist Kenny Boufadene. “We instantly felt and heard the ‘metal undertones’ of the song, and figured we should try to make a cover of it. It worked out perfectly by simply speeding it up a bit, implementing growls, double bass drums and metal-guitars. We didn’t really re-arrange anything, as it was already so well-done, we just added our touch to it! Ellie is a really talented artist, and I’m glad people seem to appreciate our tribute to her great work!”
