Nine Inch Nails Remix Presentation
The Nine Inch Nails webpage explains:
In the studio, we record everything in a multitrack format, separating all the parts onto different "tracks" that can be manifested individually. These tracks are then mixed down to two tracks - left and right (stereo) - that arrive to you in the form of a CD or Mp3. We're giving you all of the individual multitracks that were used to create the stereo ones you know. By loading those tracks into the appropriate multitrack application of your choice, you can remix and manipulate the original parts to your liking.
