In a new piece for Rolling Stone, Dan Auerbach and Patrick Carney of The Black Keys talk about the inspirations and process of creating their new album. One of the more interesting tidbits was how they came up with the title, “Let’s Rock”, for the LP. Though they are indeed a rock band who create rock songs, it turns out that the decision had nothing to do with music. “Let’s rock” was actually the last words of a convicted murderer before his electric-chair execution. The duo found an old newspaper that talked about the incident. That explains why the album cover features a depiction of an electric-chair, as well.
