Galleries began growing in both number and size in the late seventies when artists who worked in lofts wanted to exhibit their work in spaces similar to the ones the art was made in.

All of Koons's best art - the encased vacuum cleaners the stainless-steel Rabbit (the late-twentieth century's signature work of Simulationist sculpture) the amazing gleaming Balloon Dog and the cast-iron re-creation of a Civil War mortar exhibited last month at the Armory - has simultaneously flaunted extreme realism idealism and fantasy.

I'm actually not an exhibitionist at all. When you get onstage and you get under the lights playing music I feel more hidden and more alone than anywhere else. You hide behind your music and let your emotions come out through the music.
