Over the past few years, FKA twigs and Sia have been transforming pop music, leading it away from its prior bubblegum sphere and into something a bit more multi-dimensional. And despite both artists' extremely different styles, the two overlapped today in BBC Radio 1's Live Lounge. Twigs, who released her EP M3LL155X last month, covered the Australian singer-songwriter's anthemic "Elastic Heart." Bringing her own, slow-burning style to the track—replete with haunting vocals and reverbs—twigs transformed her visit into a full-scale performance, choreography and all. This, our friends, is what magic looks and sounds like.
