Mister Jelly Roll by Alan Lomax
“This musical union demanded that there be not merely acceptance and understanding, but respect and love on both sides. In this moment of ecstasy an interracial marriage was consummated, and the child of this union still jumps for joy wherever jazz is hot. Perhaps it is so wherever peoples share their treasures and a truly fresh stream of culture begins to flow. Such moments of cultural ecstasy may occur prior to all great cultural movements just as seeding precedes birth.” (Lomax’s emphasis)
—Jelly Roll Morton, 1938
