Marc Gunn is a musician and podcaster. As the autoharp-playing half of the Brobdingnagian Bards, Gunn and partner Andrew McKee developed a following with weekly performances on the campus of the University of Texas at Austin. This led to gigs at renaissance faires, science fiction conventions, and Celtic music festivals as well as parties and weddings for the pair. The group headlined at the Oscar party for The Lord of the Rings: The Return of the King.

With the Bards' calendar busy, Gunn began producing the duo's recordings. Their first effort in 1999 was Marked By Great Size followed by Gullible's Travels in 2000. The third release was 2001's instrumental Songs of the Muse, then two theme CDs A Faire To Remember and A Celtic Renaissance Wedding. 2002 saw the release of Songs of Ireland, 2003 brought Memories of Middle Earth, and their latest CD is Brobdingnagian Fairy Tales. A solo album, Soul of a Harper, appeared in 2004; he then embarked on work for Irish Drinking Songs for Cat Lovers.

The Brobdingnagian Bards band broke up amicably on September 15, 2008, and Gunn plans to pursue a solo career.
