Trent Reznor and Atticus Ross did music for the new Netflix film Bird Box, but their input for the movie wasn't announced before it debuted on Netflix. Reznor tweeted on New Year's Day, "Yes, Atticus and I scored [it] and the soundtrack is now available at [the Nine Inch Nails website]."
The site is a selling high-resolution audio version of the score -- it will be available in standard form at all digital platforms on January 25th. (premiere)
