Meg White, the duo's singer-drummer, is apparently suffering from acute anxiety and is unable to travel at this time, according to a spokesman for The White Stripes. "We hate to let people down and are very sorry," the spokesman said in a statement relayed to promoter Tom Moffatt.

A total of 18 concerts, from a Sept. 13 show scheduled for Albuquerque to the Honolulu date, were affected by the cancellation.
