If you follow Lorde on Twitter, you probably know that she loves the trip-hop producer Son Lux. So much so, in fact, that she's been covering his song "Easy Switch" pretty often lately. So, it makes sense that he'd recruit her to record some vocals on a remix of the track called "Easy (Switch Screens)." It's an amazing song, with Lorde's signature vocals sounding like a witch's incantation over shuffling beats, eerie horns, and droning synth layers. Here's hoping this signals more collaborations from these two, if Son Lux isn't too busy hanging out with Sufjan Stevens and Serengeti. Check it out.
