As soon as I got on the train, I noticed that it felt like every second passenger was wearing heavy metal clothing. When we arrived in Cologne, there were more and more of them. Once around the cathedral, the puzzle was quickly solved. On the cathedral square everything was closed off for a concert with high walls. So I was entertained for free by good music while taking pictures. Perfect. Others seemed to feel the same way and so I was able to take this picture of passersby trying to get a glimpse over the barrier walls.
