On March 8, Nine Inch Nails' The Downward Spiral celebrated its 26th anniversary. A massive commercial success, the extremely dark concept album dealt with ideas of death and morality. According to a 1997 interview with Rolling Stone, NIN’s Trent Reznor said that part of what inspired him was the unique location he was living while writing it: the home where star Sharon Tate was murdered by Charles Manson acolytes in 1969.
