Yesterday I got to see with my kids, the Blue Man Group performing in London. They opened here in November 2005, but have been around since 1991 when they launched in the USA.
It seems to be related to performance art, part comedy show through video rock animation and mime, functioning too as a critique of modern art and postmodernism, or at least just enough to be entertaining and make lots of money. I did enjoy most the moments of deliberate 4th wall breaking with the audience (interrupting the show to ridicule latecomers in the audience for instance). Anyone else seen it?
