Essen, Germany isn’t really much to look at. It is somewhat typical of many cities in der Vaterland, having been bombed-out during the second World War and rebuilt using one heck of a lot of grey concrete. It also has the requisite burned-out church tower as a reminder. Not sure what it’s supposed to be a reminder of, ar at least I’m not going to get into that here. There is a bright spot in Essen, though, and it comes once a year to Messe Essen, the city’s huge convention center complex: Techno Classica Essen.
