Listen to Nine Inch Nails on iHeartRadio

The latest incarnation of Trent Reznor's Nine Inch Nails is back to a six-man lineup.  The group was briefly down to five members last week after bassist Eric Avery stepped away, but on Friday Reznor announced that longtime Nine Inch Nails associate Robin Finck has returned. 

The guitarist has worked with the band periodically since 1994, last joining them onstage for their 2009 tour.  Reznor says adding Finck makes Nine Inch Nails "incredibly powerful and versatile."  He says they're "deep in the rehearsal process" for their upcoming outing, which starts July 26th at the Fuji Rock Festival in Japan.
