Nils Müller is an artist of many talents. He started his career by “train writing.” This form of art is ephemeral, since the works are produced on railway cars and are erased by time and by the authorities. Soon, photography allows Nils Müller to immortalize these works. However, it puts more emphasis on the action itself and transcribes by his photographs an incredible atmosphere, evidence of emotional tension. When we met Nils Müller for the first time in 2009, he had published his first book “BLÜTEZEIT” (flowering). So we met him again for 5 minutes in Cologne and have followed him to assist his actions in France and Belgium. Here is the result.
