[[Image:Wavegoodbye.jpg|thumb|200px|Tour logo from [[nin.com]]]][[Image:Wavegoodbye2.jpg|thumb|200px|Logo from bottom of tour page]]The '''Wave Goodbye''' [[Tour|tour]] took place between February and September 2009 in North America, Europe, Australia and Asia as a series of farewell dates, though NIN would be revived for touring again in 2013. During the [[2008/12/13 Las Vegas, NV|Las Vegas, Nevada]] show on December 13, 2008, [[Trent Reznor]] announced [[Alessandro Cortini]], like [[Josh Freese]], would be leaving the line-up at the end of the tour, making the show the last for both Freese and Cortini. It was also announced that after the Australian leg of 2009 dates there would be a selection of US Amphitheater dates and some European shows later in the year in the same format as Australia, following festivals.
Reznor also stated that 2009 would see Nine Inch Nails performing as a four-piece act, opting to not replace Cortini, suggesting the shows would not be of the same aesthetic visually or musically during the 2009 dates. This was confirmed a matter of days later via an entry on the nin.com homepage, confirming that the [[Lights In The Sky Tour]] ended with the departure of Josh and Alessandro, possibly indicating an entire new theme and motif for 09 tour, much like the changeover from 2006's [[Live: With Teeth]] to [[Performance 2007]]:
