Finally! After several mysterious teases, we have "Reflektor," a brand new song from Arcade Fire. And in the tradition of their game-changing interactive "We Used to Wait" video, the Montreal indie heroes have released an astounding interactive website to accompany their latest song.

An experience that involves your computer, smartphone and webcam (or mouse if you don't have one), the "Reflektor" clips allows you to partially control the dazzling otherworldly effects in a short film called Just a Reflektor. And if you have a webcam, your own face will appear in the clip. Trippy!

The video, shot in Haiti, "follows a young woman who travels between her world and our own." Watch the video over at JustaReflektor.com and check out the fascinating making-of features on the website as well. 

Even better than the video, however, is the song itself. Some songs on their upcoming fourth album were produced by James Murphy, and this track definitely sounds like it's one of them. Easily the most dance-able thing they've ever released, "Reflektor" has a persistently funky rhythm that sounds very much like it could have been on an LCD Soundsystem track. You can buy "Reflektor" here.
