Though it's been only a month and a half since Nine Inch Nails last subverted music-industry protocol with a surprise self-released instrumental album, Vulture buddy Trent Reznor is apparently getting set to put out another one, but with actual singing this time! Yesterday, "Discipline," a new NIN single was sent to radio stations, and this morning it's available for free download on the band's official Website. "We have some tour info coming … SOON," writes Trent on his blog, "as well as some other info about something else, too" (by "something else" he is obviously referring to a new album, which we can likely expect in two weeks).

"Discipline" sounds like it could've been on last May's Year Zero, which makes sense since around the time of its release, a publicist from Trent's former record label told us he'd recorded Zero and its follow-up simultaneously; whatever this forthcoming album is, we bet it's been finished for over a year. So, he tested the waters by making a quickie LP of ambient instrumentals, and when even that proved wildly successful, he decided to try it with a pop album. Smart guy. And even more so because he seems to be doing this as many times as he possibly can before everybody gets sick of these surprise Internet-release things.
