If you are prone to goosebumps, consider yourself warned: they will hit you at several key moments on Elon Twisted Measure's cover of Sia's Chandelier. Soloist Abby Franklin's voice floats over the group, and she captures the emotions of the song beautifully in an arrangement that turns an electropop anthem into a power ballad. But what gives the song depth in its arrangement is the restraint in the backs. Voice parts come in and out, and the melody jumps from a group line to the soloist — and that's where the goosebumps come in. The pacing of this song is perfect; Twisted Measure has found the perfect tempo and knows how to add and subtract voices and volume for maximum dramatic effect.

I wish that Twisted Measure had credited the soloist and arranger more clearly (it wasn't mentioned on the single's page on Loudr, which usually has a breadth of information). I also wish that the somber intro had been a little shorter — it sets a good tone for the song, but after you've heard it once, you'll want to skip directly to the more poignant moments of the performance on future listens.

Those are somewhat minor complaints, though. Chandelier is beautiful, haunting, and memorable. If you haven't heard this song yet, please go listen now. And then, figure out how you missed it when it was released — the song went viral thanks to mentions on Time.com and BuzzFeed — and for good reason. Well-earned, Twisted Measure.
