Festival-wrecking beard-rock heroes My Morning Jacket released their new album The Waterfall a month ago, and last night, they were on Conan in a musical-guest capacity. On the show, they knocked out a rousing, majestic take on “Believe (Nobody Knows),” a big and inspirational number that sounds something like an “Eye Of The Tiger” for a Bonnaroo generation. Check out the performance below.

The Waterfall is out now on ATO/Capitol.
