Nine Inch Nails, commonly abbreviated as NIN (stylized as NIИ), is an American industrial rock band formed in 1988 in Cleveland, Ohio. Singer, songwriter, multi-instrumentalist, and producer Trent Reznor was the only permanent member of the band until the official addition of English musician Atticus Ross in 2016.

Reznor recorded the band’s debut album, Pretty Hate Machine (1989), while working overnight as a janitor at a Cleveland recording studio.
