Kassel, the city of about 200,000 roughly at the center of Germany that plays host to Documenta every five years, is overrun with art tourists right now. Dealers, artists, critics, and curators (probably the largest contingent) throng the streets and the tram. They seek wifi, schnitzel, beer, and art. They are all looking for the Neue Neue Galerie, which is not to be confused with the Neue Galerie. There is too much to see and too little time. Best to keep moving. Documenta can be done in two days, really requires at least three, and can probably only be seen in full if you live in the area and can spend a few weekends wandering from place to place and savoring its many videos in full. Below, a look around the show.
