Nine Inch Nails, commonly abbreviated as NIN, stylized as NIN, is an American industrial rock band formed in Cleveland in 1988. Singer, songwriter, multi-instrumentalist, and producer Trent Reznor was the only permanent member of the band until his frequent collaborator, Atticus Ross, joined in 2016. The band's debut album, Pretty Hate Machine (1989), was released via TVT Records. After disagreeing with TVT about how to promote the album, the band signed with Interscope Records and released the EP Broken (1992). The following albums, The Downward Spiral (1994) and The Fragile (1999), were released to critical acclaim and commercial success.
