Closer

Driven by a profoundly funky, synthesized bassline and a heavily modified kick drum sample originally recorded by Iggy Pop, 'Closer' brought industrial music to the mainstream masses. Trent Reznor's lyrics utilize intensely graphic sexual imagery as a metaphor for desperate isolation and self-degradation. Despite its explicit content, the track's undeniable, mechanical groove made it an unavoidable club staple and alternative radio behemoth.
