Five years is a long time by most people's standards, but when such a period passes between albums by Nine Inch Nails, the turbulent electro-noir behemoth conducted by Trent Reznor, it's par for an increasingly elaborate course. With Teeth follows a period of intense self-investigation, a psychological shelf-clearing. It's an album that startles with its clarity, with its renewed vigour. A catalogue of grievances perhaps, like all his records, but possessed with more of a will to fight back than any other Nine Inch Nails release to date. Interscope. 2005.
