“Authorship is merely some of the point of these kinds of records, which generally serve as a mixtape declaration of self-congratulatory taste that doubles-down on the references: “Not only do I dig Bob Dylan, I dig Lucinda Williams doing Dylan. Booyah!”
Weighing in with Dylan are heavies like Rickie Lee Jones, confident stylist Shelby Lynn and the aforementioned Williams, wielding little but her rough-diamond voice, liquid guitar and a big ol’ bag of hurt.”
…”her liquid guitar”. I love that analogy!
