Mumford & Sons headlined the first US show of their Gentlemen of the Road Stopover run in Portland, ME on Saturday night. Inspired by the Telluride Bluegrass festival, the multi-band events are designed as mini-festivals in areas that normally don’t host large music events. Portland’s stop featured performances by Dawes, St. Vincent, Apache Relay, Dropkick Murphys, Haim, Simone Felice and The Maccabees, among others, and drew 15,000 fans to the city’s Eastern Promenade.

At the end of their set, Mumford & Sons invited out most of the festival’s performers for a single-along take on The Band’s “The Weight.” The members of Dawes stole the spotlight during the performance: drummer Griffin Goldsmith handled Levon Helm’s beat while frontman Taylor Goldsmith shared lead vocals. Later in the night, Marcus Mumford attended Aaron Embry’s after show at the Port City Music Hall. During Embry’s performance, he also took the stage for “Tiny Prayers.” Mumford & Sons will perform in Canandaigua, NY tomorrow.
