group accompaniment. Researcher Gayle Dean Wardlow has 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, later were 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". 1930s "Standing on the Corner (Blue Yodel No. 9)" by Jimmie Rodgers, recorded on July 16, 1930, was one of a series of recordings made by the biggest early star of country music in the late 1920s and early 1930s, based on blues songs he had heard on his travels. "Blue Yodel No. 9" was recorded with an uncredited Louis Armstrong (cornet) and Lil Armstrong (piano), foreshadowing later collaborations between black and white musicians but which at the time were almost unprecedented.

After the original recording by the Original Dixieland Jass Band in 1917, "Tiger Rag" had become a jazz standard as well as widely covered in dance band and march orchestrations.

I sit there and rock, I sit there and rock, yeah yeah yeah." Music historian Robert Palmer wrote that "the rhythmic singing, the hard-driving beat, the bluesy melody, and the improvised, stream-of-consciousness words... all anticipate key aspects of rock 'n roll as it would emerge some 20 years later." "Oh! Red" by the Harlem Hamfats, recorded on April 18, 1936, was a hit record made by a small group of jazz and blues musicians assembled by J. Mayo Williams for the
