Sienna – Jean-Michel Basquiat

Basquiat was painting on the streets of lower Manhattan before he was twenty. He started as one half of SAMO, a graffiti duo with Al Diaz that tagged cryptic, sardonic phrases across downtown New York: 'SAMO as an end to mindwash religion, nowhere politics and bogus philosophy.' When the partnership ended, he wrote 'SAMO IS DEAD' on the walls and moved on.

He had no formal art training. He dropped out of school at seventeen and slept on park benches and friends' floors. He sold hand-painted postcards and t-shirts. He gate-crashed a restaurant where the critic Henry Geldzahler was eating with Andy Warhol and handed them a postcard. Warhol bought one. The art world opened.

By twenty-one he was showing in galleries. By twenty-two he was the youngest artist ever invited to Documenta in Kassel. The paintings are dense, layered, furious: text fragments, anatomical drawings, crown symbols, crossed-out words, references to Black history, jazz, boxing, anatomy textbooks, and street signage. They look unplanned but they are not. The crossed-out words are deliberate. He wanted you to read them, then register the erasure.

He and Warhol collaborated on a series of paintings in 1984 and 1985. The relationship was complicated by the art market's tendency to treat Basquiat as Warhol's protege rather than his peer, and by the fact that Warhol, older and more established, got better reviews for the joint work. Basquiat pulled away.

He died of a heroin overdose in 1988, at twenty-seven. His paintings now sell for over 100 million dollars. He would have found that both satisfying and absurd.
