PORTLAND — The London-based folk rock band Mumford & Sons will bring its series of Gentlemen of the Road Stopovers to the United States, starting with an Aug. 4 outdoor concert on the Eastern Promenade.

Mumford & Sons — whose “The Cave” album earned four Grammy nods this year (Record of the Year, Song of the Year, Best Rock Performance and Best Rock Song) — will headline the main event. 

“The Gentlemen of the Road Stopover is based loosely upon our favorite festivals like Colorado’s Telluride Bluegrass and Scotland’s Loopallu Festivals. We want to stop off in towns where bands don’t usually tour, and celebrate the local people, food and music,” Mumford & Sons said in a prepared statement.

“We’re keen to promote the town’s local businesses and we’ll be using the local bars and venues for after-show parties, whilst working closely with the local people to get everyone involved in making these shows spectacular.”

“There will be a host of our friends playing, too, and the vibe falls somewhere between ‘travelling Victorian circus’ and ‘Victorian travelling circus’. It should be a whole lot of fun,” Mumford & Sons said.

Also playing at the Portland event will be artists curated by Mumford & Sons: St. Vincent, Dawes, The Maccabees, Apache Relay, Simone Felice and Haim.

Gates will open at noon with music starting at 2 p.m. General admission tickets go on sale at 10 a.m. Friday, June 1 , exclusively at www.gentlemenoftheroad.com. Tickets are $69, with no additional fees. A limited quantity of $59 tickets will be available beginning June 1 on a first-come, first-served basis. 

The other three Gentlemen of the Road Stopovers will be in downtown Bristol, Va./Tenn.; Page Park in Dixon, Ill.; and the legendary Fairgrounds in Monterey, Calif.
