Mumford and Sons sigh no more.

When the softly strumming guitar and the harmonious voices of Mumford and Sons fill the room, I immediately assume that I’m in for a record of calmly earnest folk music. Little do I know that the opening title track of Sigh No More will build to dark, driving bluegrass. When the lyrics tell me “love will not betray, dismay or enslave you, it will set you free,” I imagine my fist punching the air like an impassioned revolutionary.
