Nine Inch Nails primarily revolves around Trent Reznor. The multi-instrumentalist can have some pretty grand ideas for records, and he usually knows exactly what he wants. Which isn't to say that he doesn't surround himself with talented musicians, but every tour is a bit of a shake-up from the last. It's been four years since the band last toured, but Reznor may have assembled his most talented (and certainly most diverse) supporting cast yet. That diversity will come in handy, as recent album Hesitation Marks shows as wide a range as Reznor's ever displayed. Meet the new Nine Inch Nails members below.

Alessandro Cortini: This pianist has toured with Reznor before, playing the keys with Nine Inch Nails on tour between 2005 and 2008. He's also involved with his own projects, the band SONOIO and solo as blindoldfreak.


Josh Eustis: Another keyboardist, Eustis already has experience working with some of rock's biggest cult figures, including Maynard James Keenan's Puscifer. He also plays in electronic group Telefon Tel Aviv.


Robin Finck: This guitarist is the most familiar face to NIN fans, having collaborated with Reznor since 1994, and performing on tour with the band on its last tour during 2009.


Lisa Fischer: Fischer is one of the most interesting new members, considering her body of work as a background vocalist. She's sung on tour with Tina Turner, Luther Vandross and The Rolling Stones during their most recent tour. Of course, she's won a Grammy for her own work, 1991's "How Can I Ease The Pain."


Sharlotte Gibson: This vocalist comes to Nine Inch Nails from a vastly different market as well. She's worked singing background on American Idol and Duets.


Pino Palladino: Bass is more important in NIN than the average rock band, and Palladino has proven his mettle, touring with The Who to replace the legendary John Entwistle, plus he's recorded with Eric Clapton, Jeff Beck and R&B artist D'Angelo.


Ilan Rubin: This drummer got his start with Lostprophets, plus he's played with Angels and Airwaves.

That's kinda what I figured.
