Nine Inch Nails, often stylized as NIN, is an American industrial rock band formed in 1988 by Trent Reznor, who serves as the main producer, singer, songwriter, and instrumentalist. NIN's music straddles a wide range of genres, incorporating elements of industrial rock, electronic music, and alternative rock. Reznor's signature style — a blend of aggressive and melodic soundscapes, layered with dark, introspective lyrics — has been highly influential in the expansion of industrial music into mainstream audiences. Among the band's notable works are the critically acclaimed albums "The Downward Spiral" (1994) and "The Fragile" (1999).
