It's The Remix

The Arcade Fire just released a music video for "Black Mirror". They made a website for the video and you are given the option of turning on and off 6 different channels/tracks from the song. So, you can mute the drums, or vocals or strings, which really means you can kind of remix the song. I've had fun muting and bringing back the drums track, or soloing the vocal and drum track. Check it out.
