Mumford and Sons brought their new electrified sound to Saturday Night Live yesterday (April 11).

Performing their latest tracks, "The Wolf" and "Believe," off their upcoming album, Wilder Mind, the London band showcased that they have really moved on from the folk, jam band sound to a more rock and roll vibe. Kicking off "The Wolf," the members jump on it with lots of energy and prove that they have graduated from their former acoustic sound. Putting everything they have into their instruments, the performance quickly grabs you and doesn't let go. You feel every guitar riff and drum beat -- knowing that they mean everything they play. You can watch the full performance above.

For their second set on the show, Mumford & Sons slowed things down a little bit with "Believe." Showing the crowd more of the emotion and earnest playing that made us fall for them in the first place, the track has a refined and epic quality that grows as the song progresses. Frontman Marcus Mumford even puts his guitar down toward the end, picks up a tambourine and starts belting on the mic -- showing us more of that unbridled emotion.

"I don't even know if I believe / I don't even know if I believe / I don't even know if I believe / Everything you're trying to say to me," Mumford belts into the mic. You can see the band perform "Believe" below.

Mumford & Sons looked like they had a blast on SNL and posted behind-the-scenes pics on their Instagram. They also announced that the video for "The Wolf" will be premiering tomorrow (April 13) by sharing a clip of the visual, which you watch below.
