You never really know what to expect from one of Justin Townes Earle’s live performances. He could be fired up and stomping his feet all over the stage. Or he could decide to play everything in half-time like he did at this year’s Americana Music Festival. When Earle arrived for his Live @ CMT set, he was in a thoughtful, mellow mood, and his bluesy songs about acceptance and self-image took on a gorgeous, if heartbroken, form. With his distinctive guitar style, Earle turned in exclusive performances of “Memphis in the Rain,” “Look the Other Way,” “Am I That Lonely Tonight” and “Ain’t Glad I’m Leaving.” Take a look.
