Episode 324: It’s hard to believe that Nashville’s SteelDrivers have been making their unique brand of hard-core string band music for nearly twenty years. They were the vehicle through which many of us were introduced to the epic voice of Chris Stapleton, back when he and Mike Henderson co-wrote that band’s high impact debut album of 2008. When Henderson and Stapleton had to move on, the band pulled its greatest trick, bringing on great new voices, growing bigger, and building a legacy that’s like nothing else in 21st century bluegrass. In Episode 324 of  The String, Craig talks with original members Mike Fleming, bass player and baritone vocal, and Tammy Rogers, the fiddler and harmony singer who now leads the way with the band’s songwriting. We talk about the whole ride, up to the new album Outrun, out now on a revived Sun Records.
