Mark is best known for unique songwriting and for the raucous barroom sounds of his urban blues/roots rock ensemble, the Van Dorens, a revolving-door collective of dedicated musicians and production collaborators.. His originals, such as "When God Finds the Time", "Fritos, BBQ and Scotch", "I'm Going Blind", "One More Coat of Paint", "How Do the Blind Become So Famous?" and "The Drinks are On Me" take on traditional genres and weave them into contemporary, vital music.
In his instrumental roots guitar CDs titled "Roadside Americana" and "Mirage Cartography", Mark pays quiet homage to country blues greats such as Blind Blake, Mississippi John Hurt and Rev. Gary Davis, as well as next generation influences including John Fahey and Leo Kottke.
Most frequent among his session collaborators is the Grammy-winning Memphis producer/engineer Jeff Powell. Mark's created albums with Grammy-winning producers Jim Gaines, Terry Manning and the late John Hampton.
Mark is principal owner of Radiation Records Inc. and its publishing affiliate Last Warning Music.
