In 1917, with the USA just a short month from entering the war, the first ever Jazz (or 'Jass') record was released.
The splendidly-named Victor Talking Machine Company (who survive in the form of RCA Victor) was responsible, having a month earlier established a recording studio in - not New Orleans or Chicago, but New York.
And the band? An all-white five-piece called The Original Dixieland Jass (late changed to Jazz) band and the tracks - Livery Stable Blues (the 'B' side) and Dixie Jass Band One Step.
The record took New York by storm. And the rest, as they say, is history...
