Mark Lee Townsend is an American multi-instrumentalist and record producer best known as guitarist for the Christian rock band dc Talk and as the long-time producer for Christian rock band Relient K. Townsend's career started as a member, singer, guitarist and songwriter for the pop and Christian band[1] Bash 'N The Code from 1986 through 1991.

At the Cornerstone Festival 2000, he appeared doing an acoustic act where he ended his show with a rendition of Queen's "Bohemian Rhapsody".

A sideman's greatest asset is the chameleon-like ability to adapt to a variety of musical genres as well as imitate the signature sounds of other players.

On the other hand, a session player has truly reached the top of the profession when he's in demand to add his own signature sound to a recording or live tour.

In 2011 he was reportedly producing The Lasting Hope's debut EP Sunsets and Second Chances.
