It’s happening all over again, Daft Punk fans. We’re guessing you remember those hectic hyper-ventilating first moments last fall when you found out that you could catch a sneak peak of the French electro-duo’s work on the TRON soundtrack by poking around on the soundtrack’s official website. Well, it looks like those days are upon us again as the remix album for the film’s soundtrack has made its first presence on the web. By typing “M83″onto the surface of the official website, you can listen to three clips from Daft Punk’s upcoming remix album for the TRON Soundtrack, TRON LEGACY R3CONFIGUR3D, which is set to be released on April 5th. We’re not positive which three cuts we’re hearing, but the middle track sounds to us like M83’s work.
Too lazy to go try it yourself? Don't worry. I recorded and uploaded a video for anyone interested. :)
