Gotta love Trent Reznor! His newest project with wife Mariqueen Maandig, and Atticus Ross, How To Destroy Angels, album isn't even out but yet they are offering the multitrack files for their latest tracks "A Drowning" and "The Space In Between" off their debut EP for fans to download for free and remix.
If you aren't familiar with the NIN remix community you can find instructions on how to obtain the files/stems on HTDA's official Facebook page. These files are simple to load in any audio production software to get these files and many others including Nine Inch Nails and even Saul Williams, go here, login or register and have at it. Hell I'll even throw in a remix I did back in the day for good measure, just don't laugh.
