"The show must go on," ailing frontman Trent Reznor wrote in a brief message posted at NIN's website Thursday (3/2). True to his word, Reznor and company performed their scheduled concert in Quebec City last night, but the show apparently sapped Reznor.

"Tonight's Nine Inch Nails performance at Scotiabank Place in Kanata, [Ontario] has been postponed until further notice due to illness," reads a new message posted at NIN's site today (3/3), which goes on to say that "additional information will be posted in the next couple of days."

That additional information might take the form of a summer-tour announcement that could include a rescheduled Kanata stop; as it stands now, NIN has rescheduled the missed Portland, ME, show for June 21, and is expected to unveil details of the summer leg soon.

The Kanata show marks the third postponement this week for Nine Inch Nails.

"I'm the sickest I've felt in a long time and there's no way I could've pulled off a show tonight," Reznor wrote in a Monday (2/27) posting at his website about that night's postponed show in Amherst, MA. "Please know I hate to do this, sorry for the inconvenience."

The Amherst date is now scheduled to take place March 10.

NIN has been on the road since last spring in support of its May 2005 release, "With Teeth," which features the singles "Only," "Every Day Is Exactly the Same" and "Hand That Feeds."

On April 4, NIN will issue an "Every Day Is Exactly the Same" EP that will include remixes by Interpol, DFA, Photek, EL-P and Richard X. The cover art and track listing are posted at NIN's website. "With Teeth"--NIN's first new studio set since 1999's "The Fragile"--debuted at No. 1 on The Billboard 200 chart.
