There was rock and roll years before anyone got credit It was when a record became a big hit and it was noticed that it went in the record books:
"Crazy About My Baby" by "Blind Roosevelt Graves and brother Uaroy, recorded in 1929, was a rhythmic country blues with small group accompaniment. Its stated that this "could be considered the first rock 'n' roll recording". The brothers also recorded rhythmic gospel music. The Graves brothers, with an additional piano player, were later recorded as the Mississippi Jook Band, whose 1936 recordings including "Skippy Whippy", "Barbecue Bust" and "Hittin' The Bottle Stomp" were highly rhythmic instrumental recordings which, according to writer Robert Palmer, "..featured fully formed rock and roll guitar riffs and a stomping rock and roll beat"
