If you've heard London Grammar before, you know their musical style is not on the energetic side. But the lead singer's voice, over their production, is like a slow-motion knockout punch from Mike Tyson. And London Grammar over dance beats is like a Mike Tyson punch set to classical music. You're just in awe. And that's the feeling you get when you listen to the Arty Remix of "Hey Now". So much energy, so much life...so much London Grammar crooning. Show love and check out their Facebook, Twitter, Soundcloud and website. Check out Arty's Soundcloud for more.
