Here's a link to one of their YouTube videos, Little Lion Man . (Excuse the 4-letter word. I'm no fan of expletives but, you'll see.) Here's another with no colourful language, I Will Wait, live with the massive audience appreciating their efforts.
We have both of their albums in our house, on our electronic devices and on several playlists. The CD's sit ready to play in the kitchen where morning wake-up music is often Mumford and Sons.
Wake up. Wiggle, dance, and play air banjo! Stomp your feet, sing along and feel uplifted.
Once you've seen a video, you can always imagine them playing for you and you'll feel even better.
