From the alternate history science fiction novel Wrack & Roll by Bradley Denton (1986). African American private in the U.S. Army during an alternate history World War II where the Allies nuke Berlin and march on Moscow. He invents the genre of "Wrack & Roll" music, a sort of WWII punk rock.
He dies in a suspicious car crash in the 1950s. Or, a la Elvis, is he really still alive?
