Mark is a Glasgow-based software developer who somehow fell into radio presenting as a sideline. Having no idea how to operate a radio studio, he pre-records his "Variant Thirteen" shows which are usually a mix of psych, experimental and/or avant-garde electronica, wyrd folk plus a smattering of more standard indie/alternative/shoegaze/rock to keep listeners on their toes! Can often be found in Pure Gym Shawlands.
