Nine Inch Nails fluently speaks the language of dark and emotional electronics. From the angst ridden industrial-pop that distinguished the debut album Pretty Hate Machine to the more introvert and focused sound of the latest album effort The Slip, the act never loses sight of the most important element in music. Substance. Twenty-five years after the formation in 1988, Nine Inch Nails is a prime example of how quality stands the test of time.
