Does anyone know when they're releasing this, if ever?? Or if it's available somewhere and I'm just crap at looking....

Do you mean The Box with Cameron Diaz, James Marsden & Frank Langella? Cause if you do, I'm pretty sure it's not Arcade Fire....

No, it definitely is Arcade Fire

It would appear you are right. After googling Win Butler, I found out he's the lead singer. It's just labeled as 3 individual artists, I don't know why. It should just be labeled as "Music by Arcade Fire"
