There’s a good chance that the name “Scott Billington” is on the back of your favorite album. Make that “albums.” As a long-time music producer for Rounder Records, Billington has tended the most fertile ground of American music. Clarence “Gatemouth” Brown, Charlie Rich, Solomon Burke, Irma Thomas, Johnny Adams, James Booker, Dr. John, Buckwheat Zydeco, Duane Allman, the Dirty Dozen Brass Band and the Soul Rebels make up only a partial list of the artists with whom Billington has worked. He’s also collaborated on projects featuring Woody Guthrie and the recordings of musicologist Alan Lomax.
