When “Americana” emerged more than 20 years ago, Robbie Fulks rose to the top of the heap in no time flat. He could do no wrong, cranking out multiple albums of his quirky yet deeply traditional music. From classic honky-tonk to screaming rockers to lilting bluegrass, he does it all. Fulks’ newest release is Gone Away Backward, a deceptively quiet acoustic album with some deep dark political undertones. And the covers? Awesome. Totally non-ironic takes on the likes of Michael Jackson, Cher, and ABBA pop up on his live set lists, and somehow fit right in with his own great material.
