ProgDay is the longest running progressive rock festival in the world. I have been creating the festival art since the first show in 1995. This is a collection of art from over the festival's history.
The pieces generally include a direct music reference (1996 and 2001 do not), and since ProgDay is an open-air festival held in the country, there is usually a sun/nature/venue reference (2000 and 2002 do not).
