Interesting if there's any connection here.

>"Behind the door of all doors" refers to a place behind our usual space - a transition to the lost mysticism of everyday life. The piece, merging video and sound, eliminates connections between the senses' common attributions and opens a door to associations, to a space between reality and fiction - it's the place behind the door leading to all doors. It is light, power, space, memory, and risk – a transcendental falling – standing at the threshold to the unknown.
