Nothing minor happens in a Florence Welch song. While most of us worry about hangnails or roaming charges, her mind is gripped by images of blindness, despair, suicide and other symptoms of love. On Unplugged, she intensifies the turbulence of her LPs and adds two covers, including a hushed "Try a Little Tenderness" that stands as the best version since Otis Redding's. While the harp, violins and choir remain delicate, Welch erupts into wild, simmering high notes, most notably on "No Light, No Light." Her singing is stunning; this should be credited to Florence and the Vibrato.

“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.
