If some of our works are symphonies, then wrapped walkways was chamber music.

Now, to describe the process of the Wrapped Reichstag, which went from 1971 to '95, there is an entire book about that, because each one of our projects has its own book. The book is not an art book, meaning it's not written by an art historian.

We have created indoor installations inside museums, like the Wrapped Floor at the Museum of Contemporary Art in Chicago in 1968, and not monumental at all by any standards.

I escaped from my home country, Bulgaria, to Czechoslovakia and then to the West.

All our projects are like fabulous expeditions. The story of each project is unique. Our projects have no precedent.

Chamber music -- a conversation between friends.
