Barron works with mixed media, notably discarded box packaging and old roof slate as well as with oil on canvas and paper. His work tends towards a minimalist, contemplative style and, if it is about anything, he thinks it is about the passage of time made corporeal through certain images, surfaces and textures.

In the oil on canvas works he applies a flat surface with bold, clean lines as opposed to the scored, eroded, textured surfaces of the card and slate pieces.
