NINE INCH NAILS mainman Trent Reznor recently spoke to Rolling Stone magazine about the group's upcoming CD, "With Teeth"."I had plenty of life experience to draw from while working on this record," Reznor said of the CD, NINE INCH NAILS' first album in six years. "I was getting sane while the world was going crazy." Due May 3, the follow-up to 1999's "The Fragile" features a guest appearance by former NIRVANA drummer/current FOO FIGHTERS frontman Dave Grohl. "I wrote some of these tracks with a Grohl-esque performance in mind," said Reznor. "I asked him if he was into it and that was that." Added Reznor, "This record is probably more honest than anything I've done." Trent Reznor and the new NINE INCH NAILS lineup — guitarist Aaron North, bassist Jeordie White (A PERFECT CIRCLE, ex-MARILYN MANSON), keyboardist Allesandro Cortini and drummer Jerome Dillon — will kick off a North American theater tour in April.
