PORTLAND — Tickets for the upcoming Mumford & Sons concert sold out in about 30 minutes this morning.

Tickets for the Aug. 4 music festival on Portland’s Eastern Promenade went on sale at 10 a.m. on the band’s website and were sold out in about 30 minutes, said Lauren Wayne, the show’s local promoter. Tickets are $69, general admission.

Wayne said the quick sellout is probably due to the fact that Mumford & Sons is doing only four U.S. shows this summer. She said tickets to the show were purchased by people from all over the country.

Wayne wouldn’t say how many tickets were sold, but the city has limited capacity for the event – on city property – to 12,500. Wayne could not say if more tickets will become available, but said that people should regularly check for updated information on the show at Statetheatreportland.com
