After Trent Reznor came storming out of the darkness with this explosive 1989 debut, industrial music would never be the same. Nine Inch Nails' mastermind moans and growls over a brilliantly messy clatter of synths, guitars, drum machines, and samples, unleashing his rage and dread through the crunchy rock grind of "Head Like a Hole" and the punchy synth-pop of "Terrible Lie." He then scrapes rock bottom with haunting piano dirge "Something I Can Never Have" before seeking catharsis in the sticky, funked-up "The Only Time."
