1. Art in the Streets, MoCA (April 17 to August 8, 2011)
Jeffery Deitch's landmark exhibition, Art in the Streets, celebrates the diversity of graffiti and street art. With aid from Roger Gastman, rich archival material balances a staggering array of large scale installation from a who's who of the street art scene—Banksy, Invader, ESPO, Mr. Cartoon, and many more. Art in the Streets is both celebration of achievement and validation of latest major wave of outsider arts. Sadly, the Brooklyn Museum's proposed hosting of a traveling version has been stifled for financial reasons. Get to LA before the August 8, 2011 close date.
