The week before last Arcade Fire's Win Butler had a nice long chat with Amy Phillips about Mirror Noir, the new documentary about the making of Neon Bible and subsequent tour that the band just released in an array of configurations. As part of the promo push for the doc they've just released an mp3 of "Burning Bridges", an instrumental version of a song called "Burning Bridges, Breaking Hearts" that the band has played live for a few years. Just gotta cough up a working e-mail address and it's yours.
