Ok next chapter in my art !! My Dissertation !!

Thanks to mother nature am nursing a nasty chest infection so as l am in bed l have been reading my research books and feel l am making a break through. Ok so my title is Theatricality within contemporary art but have  also been looking at the space   these artist use, space   and why they  choice it?  are they drawn to the area around them or maybe its a emotional choice.
Kabakov says the the "viewer finds himself in side of it, engrossed in it" walls are required to separate the viewer from the external world much like a picture frame of the edge of a painting.
