A native Texan who resides in New Mexico, Gunn is known for the unusual 10-string touch guitar that he plays. From the blistering live recordings at the Royal Albert Hall in London with David Sylvian and Robert Fripp ("Damage", Virgin Records) to ten years recording and touring with King Crimson – a group many contend as the most aggressively adventurous rock band of all time – Gunn is associated with a constant stream of cutting-edge projects.

In addition to the powerful performances and recordings of his groups Tu-Ner, KTU, 3Below, The Security Project and the multi-media Quodia, Gunn has toured and/or recorded with John Paul Jones, Brian Eno, Maynard J. Keenan's "Puscifer", Vernon Reid, Azam Ali, David Hykes of the Harmonic Choir and Steven Wilson of Porcupine Tree.

When not on the road, Gunn continues his work scoring for TV/film, runs his own media label (7d Media) and coaches musicians in the creative process.
