Mumford & Sons + Local Natives

Once known for writing banjo-picking, foot-stomping folk-rock anthems, the lads of Mumford & Sons have comfortably settled into their new identity as radio-friendly rockers. The group's latest album, Delta, takes Marcus Mumford's vocal harmonies and places them atop moody electronic compositions that might as well be castoffs from a Coldplay record. Expect to hear plenty of the group's sleek new tunes at this special 101WKQX holiday concert, accompanied by the twangy choruses of smash hit tracks like "I Will Wait For You" and "The Cave." California rockers Local Natives open the show.
