The B-sides Festival is an annual alternative music festival which takes place on the Sonnenberg near Lucerne. In the time between 2009 and 2013 Felix Pfäffli worked in close collaboration with the organizers of the festival. Every year they changed their design from ground up. Exhibitions were organized, comic magazines released or records pressed. Thus, over the years, a wonderful design history has emerged which is today being carried on by other local designers.
