Nine Inch Nails [SEP] Introduction
Nine Inch Nails, commonly abbreviated as NIN and 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. The band's debut album, "Pretty Hate Machine" (1989), was released via TVT Records. After feuding with TVT about how to promote the album, Reznor signed with Interscope Records and released the EP "Broken" (1992). The following Nine Inch Nails albums, "The Downward Spiral" (1994) and "The Fragile" (1999), were released to critical acclaim and commercial success.
