Nine Inch Nails is a critically and commercially successful American band formed in Cleveland, Ohio in 1988 by Trent Reznor. NIN's songs cover a range of genres: "The Perfect Drug" has the flavor of drum and bass, "Down in It" influenced by early Skinny Puppy, "Happiness in Slavery" is tinged with industrial metal in the vein of Ministry, "The Frail" is a melancholy piano piece, and most of Pretty Hate Machine could be considered dark electronic pop in the style of Depeche Mode.
