Harmer and his wife Kate have welcomed their first child together, so the musicians have rescheduled their Wednesday night (30Sep15) show in Missoula, Montana and a concert in Spokane, Washington, originally set for Thursday (01Oct15).

The news was announced in a statement posted on the band's website.

It reads, "Congratulations to Death Cab's Nick Harmer and his wife on the birth of their daughter! Unfortunately, as a result, we need to postpone the Missoula show tomorrow, September 30, and Spokane on Thursday, October 1... Thanks for understanding."

The Spokane gig is now set to take place on 15 December (15), but a new date for Missoula has yet to be confirmed.
