A veteran touring ace of the Nashville music scene, Mark has held down both the bass and Musical Director positions with superstar Carrie Underwood for over 15 years. In this episode we get to hear about Mark's early Gospel influences, his vintage P-basses and what it entails to be the MD for an artist who does everything from unplugged specials to arena shows to collaborations with a symphony orchestra. Mark also talks about his recent sessions for rapper DMX and the one time a bass DI box led to Steven Tyler singing two extra songs. Intrigued yet? Mark is one of the most soulful players in Music City and a gem of a guy who graciously invited us into his home for the recording of this episode.
