There are even galleries and museums completely devoted to it, here and in Europe. As an artist who has been doing installation art since 1979, the explosive growth of my chosen practice is both satisfying and frustrating. Further, installation's insistence on the importance of multiple fragments of sensory information and context is part of my own fascination with the art form. But the deluge of work is frustrating too. There is a lot of work being created and very little analysis of it.
Many reviews are simply descriptive.
When the writing does engage the work's content it often leaves unconsidered the form itself. Clearly installation is a widely diverse and idiosyncratic art form. It would be impossible to come up with a simple definition that included everything artists are doing with it. But there are junctures where installations come together. One of these is space.
