Nine Inch Nails frontman Trent Reznor has admitted it's time to reinvent the band.

"At this point, I want to switch things around a bit. As a rock band configuration, Nine Inch Nails has done it and we've done it again," Reznor said.

"I see other ways I can present the material in concert – more challenging, something new. I don't want it to go stale. The idea of five guys playing loud music for two hours – while it's the culmination of fine tuning over a lot of years – has got to change once finances come into play, especially performing in markets outside of the mainland US. I want to whittle things down."
