Pretty Hate Machine wasn't a hit when it was released; it charted in 1990 and stayed on the charts for years afterward. By the time Reznor assembled a band for the first Lollapalooza tour in 1991, the group had a sizable following that only grew with NIN's ferocious performances on the tour. Legal troubles with his record company delayed the release of a second album; in 1992, he released a stop-gap EP, Broken, that was harder and more abrasive than the debut, yet still conformed to conventional song structures; it debuted in the Billboard Top Ten. With their second full-length album, Reznor showed his true roots -- '70s progressive rock. The Downward Spiral was promoted as a concept album, a cohesive piece of work; it also featured ex-King Crimson guitarist Adrian Belew. Still, NIN is able to straddle two seemingly opposing genres easily, gaining alternative and mainstream hard rock fans alike; whether he likes it or not, Trent Reznor is the man that made industrial palatable for pop fans.
