I do not know AM radio. Since he has as profile pic of the famous painting "The Wanderer" by Caspar David Friedrich, I suppose he is a man. His installations are very special. Only a few objects and lots of room. This will make you relax and creates space for your ideas. Enjoy the beauty and take the chance to shoot great photos. Since he has announced plans to close its sims very shortly, you should not postpone the visit too long.
