NATO says no to Arcade Fire in Portugal.

Arcade Fire was scheduled to play a show in Lisbon, Portugal on November 18, but now Billboard reports that "security concerns" have forced the cancellation of the show. The problem: A NATO summit is in Lisbon November 19-20.

According to the band's reps, the show's promoters were informed that the venue, the Atlantic Pavilion, would be unavailable. The band offered to reschedule the show for a day earlier, but summit organizers said it was really not do-able. I think it has to do with a NATO summit that will take place at the same time as the concert. but who knows?
