Berlin is the city where you can have free concerts all over the year and the day. More or less sophisticated, on various rhythms and sung more or less correctly, for money or simply for fun, I met during my trips in the city many kind of artists. Now, when it's summer time, the artists went out of the dark - but freshly cold - U-Bahn or S-Bahn and have open air concerts. The latest one I attended - for 5 minutes, less than 24 hours ago - was in PBerg, with this funny band of musicians. I don't know their names, what they were singing about or why. Just entered the mood of a sunny evening, took some pictures and went home.
