The music video for "Closer" was directed by Mark Romanek and received frequent rotation on MTV, though the network heavily censored the original version, which they perceived to be too graphic. The video shows events in a laboratory dealing with religion, sexuality, animal cruelty, politics, and terror; controversial imagery included a nude bald woman with a crucifix mask, a monkey tied to a cross, a pig's head spinning on some type of machine, a diagram of a vulva, Reznor wearing an S&M mask while swinging in shackles, and of him wearing a ball gag.  A radio edit that partially mutes the song's explicit lyrics also received extensive airtime.Critical response to The Downward Spiral has generally been favorable, and retrospective reviews regard it as one of the most important albums of the 1990s. It was included in several publications' best album lists: in 2005 the album was ranked 25th in Spin's list of the "100 Greatest Albums, 1985–2005", and in 2003 Rolling Stone ranked the album number 200 on their "The 500 Greatest Albums of All Time" list. Blender named it the 80th Greatest American Album. It was ranked No. 488 in the book The Top 500 Heavy Metal Albums of All Time by Martin Popoff. In 2001 Q named The Downward Spiral as one of the 50 Heaviest Albums of All Time; in 2010 the album was ranked No. 102 on their 250 Best Albums of Q's Lifetime (1986–2011) list. After The Downward Spiral's release, Reznor produced an accompanying remix album entitled Further Down the Spiral, the only non-major Nine Inch Nails release to be certified gold in the United States and among the best-selling remix albums of all time. It contained contributions from Coil with Danny Hyde, electronic musician Aphex Twin, producer Rick Rubin, and Jane's Addiction guitarist Dave Navarro, among others.After the 1994 release of The Downward Spiral, the live band embarked on the Self Destruct Tour in support of the album. The stage set-up contained dirty curtains which would be pulled down and up for visuals shown during songs such as "Hurt". The tour debuted the band's grungy and messy image in which the members would come out in ragged clothes slathered in corn starch. The concerts were violent and chaotic, with band members often injuring themselves, and they would frequently destroy their instruments at the end of concerts, attack each other, and stage-dive into the crowd. The tour reached its widest mainstream audience with a mud-drenched performance at Woodstock '94 that was broadcast on Pay-Per-View and seen in as many as 24 million homes. Nine Inch Nails received considerable mainstream success thereafter, performing with significantly higher production values and adding theatrical visual elements to the live show. Supporting acts for the tour included The Jim Rose Circus and Marilyn Manson. Released in 1997, the Closure video documented highlights from the tour, including full live videos of "Eraser", "Hurt" and a one-take "March of the Pigs" clip directed by Peter Christoperson. Around this time, Reznor's studio perfectionism, struggles with addiction, and bouts of writer's block prolonged the production of The Fragile.
