Before he became an Allman Brother and started Gov't Mule, this power-blues singer-guitarist was a Nashville cat, playing and writing country-soul music. Man in Motion is a swing back to that hardy romanticism, with more Memphis in the mix and a plaintive poise in Haynes' vocals and solos. "Man in Motion" and "River's Gonna Rise" roll at a gospel-funk clip that would fit the Hi-era Al Green. The sax-and-clavinet strut of "Sick of My Shadow" evokes Traffic's Dixie-prog period. And Haynes has a worthy successor to his longtime Mule-encore hymn "Soulshine" in "Save Me," a ballad of need and plea that feels like benediction.

“Is It True”

As the British Invasion reached its peak in 1964, Brenda Lee went from Nashville to London to record one of her hardest-rocking hits, her perky vocal backed by a stuttering, squalling guitar. That guitar was played by session musician Jimmy Page, yet to skyrocket to fame with first the Yardbirds and then Led Zeppelin. "She said to me, 'I've come here to make a record with the British sound,'" remembered producer Mickie Most. "She felt she wouldn't get the same sound in Nashville because they're only just catching up on the British beat group sound of about six months ago."
