A piece from the Nation (via Yahoo) has a lengthy article on the New York graffiti-art scene in the 1970's/80's (I think that's what it's about ... I'm out of coffee!). Inter alia, the piece focuses on the work of Jean-Michel Basquiat (whom I've never heard of) and mentions:

Basquiat's heroes were black sports stars such as Joe Louis, Sugar Ray Robinson, Jack Johnson and Muhammad Ali, and jazz musicians like Parker, Miles Davis and Dizzy Gillespie, though in terms of the number of works dedicated to him, Charles the First reigns supreme. These range from the stark Now's the Time--in the form of a black phonograph record, ninety-two and a half inches in diameter, with Parker's tune "Now's the Time" scribbled in white paint over "PRKR"--to works consisting largely of lists, like Discography, written in white against a black background, with the names of Parker's fellow bebop revolutionaries (Miles Davis, Max Roach and the others) as well as the names of pieces recorded on "NOV. 26, 1945." The use of lists is another Twomblyism. A wonderful example is Jawbone of an Ass, in which what may be a crude self-portrait as Rodin's Thinker occupies a space in the upper left corner and surveys a scroll of historical names, including Achilles, Sappho, Cleopatra, Anaxagoras, Aristophanes, Sophocles, Socrates, Alexander the Great, down to Harrison, Tyler, Transcendentalism and Perry--with, again, a crude drawing in the lower right corner of a black figure saying "Yup!" and hitting ("Bip") a white figure with "Grrr" in a thought balloon over his head. It is, in my view, less a cartoon of racial strife, or even of the black specter haunting the white imagination, than a symbol of history as a pageant of war, since the scroll lists so many ancient battles and famous heroes--Hannibal, Hamilcar, Scipio, Alexander the Great, Spartacus, Julius Caesar. These are not the kinds of names that turn up on burners.

FWIW ...
