Radiohead’s Thom Yorke and Jay-Z are among a group of artists and musicians who will look to raise awareness to water conservation by transforming New York City water towers into public works of art.  According to The Huffington Post, the initiative is being put together by the non-profit group Words Above the Street. In all, some 300 rooftop water towers will be wrapped in artwork for 12 weeks in the spring of 2013.
