This instantly reminded me of this article from the Washington Post: http://www.washingtonpost.com/wp-dyn/content/article/2007/04...

It is from in '07, when violinist Joshua Bell played at a Metro stop in DC. The crux of the article touches on how much presentation and framing affect our perception of art. It has some interesting quotes and insights from Bell on what it feels like to go from playing halls getting paid "$1,000 a minute" to playing for a marginally less receptive crowd.
