Luther Dickinson has spent years rocking loud and hard with the North Mississippi Allstars, the Black Crowes, and the Word. But at heart, he’s an acoustic guitarist, and on the new Blues & Ballads: A Folksinger’s Songbook, Volumes I & II (New West), he’s taken songs from his catalog, re-recorded them as folk songs, and turned his back pages into a celebration of community and family, including his father, legendary producer Jim Dickinson.
