The Neon Demon is the latest film from Drive director Nicolas Winding Refn. The original music is by Cliff Martinez, but its soundtrack does feature an original song by Sia produced by none other than Diplo. “Waving Goodbye” is a creeping, clanking, and ultimately cacophonous electronic pop-rock anthem — because Sia doesn’t really traffic in anything but anthems — and I like it better than anything she’s released since “Chandelier.” Listen below.
