Brain (1985) is at once a sculpture, a self-archive, and a monument to the city that made Basquiat. Twenty-seven painted wood blocks, each covered with reproductions of his own drawings — masks, faces, anatomical diagrams, and painted evocations of jazz record labels including Charlie Parker's 1947 recording Now's the Time — are stacked into a structure topped with a bootblack stand of the kind once common on the streets of New York. The gesture toward Duchamp is deliberate: the bootblack transformed into a readymade plinth, the work signed "BRAIN©" in the same spirit that Fountain bore "R. Mutt," transplanting Basquiat's street identity into the tradition of the found object while refusing its characteristic silence. Critics who had categorized him as a Neo-Expressionist painter were unprepared for the move; Basquiat, characteristically, was indifferent to their expectations.

The boxes function as a kind of three-dimensional notebook — a recycling and reframing of his own imagery that prefigured the color Xerox machine he would later install in his studio specifically to copy his earlier work. Basquiat later exhibited Brain at Area, one of the defining clubs of downtown New York in the mid-1980s, occasionally serving as a guest DJ on the same nights, the art object and the social space collapsing into each other. The bootblack stand carries its own history: a piece of street furniture associated with a profession that was already disappearing, it transforms the sculpture into a quiet monument to the everyday labor that kept the city moving. At four feet tall, Brain is an intimate skyscraper — raw, liminal, and thoroughly alive to the world it came from.
