Fun fact: Clark and Yoakam were the opening acts on the tour that Eric Church just finished. On this show, he opened for them, and it seemed somehow fitting. Clark can write a hell of a song, and “added gravity” is just about the best-possible use of Yoakam unless you’re making a Panic Room prequel. If the Grammys are going to be all slow songs and nothing else, they could use more of that low-key elegance.
