In the 1970s, Jean-Michel Basquiat and his friend Al Diaz were enrolled at City-As-School, an alternative high school in Manhattan. They came up with the phrase “SAMO,” an abbreviation for “same old shit,” and by 1978 they were spray painting satirical advertising slogans on Lower East Side buildings. SAMO was their tag. Within a year, Basquiat had been featured in the Village Voice and had befriended Keith Haring, Kenny Scharf, and the performance artist John Sex. He would soon be making $1.4 million a year. This show focuses on the world of spray cans, subway cars, and parking lots. How did street artists go from outlaws to leaders of a global cultural movement? The show is curated by Jeffrey Deitch. —Elena Clavarino
