Empfangshalle
Empfangshalle (literally lobby) is the name of a German performing art duo. It was founded by Corbinian Böhm and Michael Gruber in Munich ( Germany) in 1995.
Medium of their works is the society. They perform their art projects in the open, especially in popular places. Their art projects - more often than not - are a mystery to the viewers and often cause confusion. A typical example was the staged "Gei hin hol" [gei: hi:n ho:l] mega-poster action with incomprehensible foreign language messages in Munich (2005).
