Howard, the Alabama Shakes frontwoman, steps into Jack White's Third Man Records lab to take on "I Wonder," a Vietnam-era tune by Seventies sugar-man Rodriguez. Backed by one of White's touring bands, she and soul singer Ruby Amanfu turn in a sisterly workout with a reggae breakdown – what Bonnie Raitt might sound like if she went through a down-home garage-rock phase.

“More Than a Feeling”

Boston mastermind Tom Scholz was as surprised by anyone when he sent his unsolicited demo to record labels and got back a positive response. Scholz said, “I couldn’t believe it. Nobody knew who we were, so I wouldn’t even say we were struggling. It was groveling.” Part of the credit for the interest must go to the anthemic rock number "More Than a Feeling." Inspired by the Left Banke's 1966 hit "Walk Away Renee," Scholz worked on the song for five years in his basement studio before it was released on this album.
