Delta Blues

 The Delta blues is one of the earliest styles of blues music. It originated in the Mississippi Delta, a region of the United States that stretches from Memphis, Tennessee in the north to Vicksburg, Mississippi in the south, the Mississippi River on the west to the Yazoo River on the east. The Mississippi Delta area is famous both for its fertile soil and its extreme poverty. Guitar and harmonica are the dominant instruments used. The vocal styles range from introspective and soulful to passionate and fiery.

Origin
Delta blues music was first recorded in the late 1920s. The earliest recordings were by the major labels and consist mostly of one person singing and playing an instrument, though the use of a band was more common during live performances. Some of these recordings were made on field trips to the South by record company talent scouts, but some Delta blues performers were invited to travel to northern cities to record. According to Dixon & Godrich [1981], Tommy Johnson and Ishman Bracey were recorded by Victor on that company's second field trip toMemphis, in 1928. Robert Wilkins was first recorded by Victor in Memphis in 1928, and Big Joe Williams and Garfield Akers also in Memphis (1929) by Brunswick/Vocalion.
Son House first recorded in Grafton, Wisconsin (1930) by Paramount. Charley Patton also recorded for Paramount in Grafton, in June 1929 (and again, at the same location in May 1930). In January and February 1934 Patton visited New York City for further recording sessions. Robert Johnson travelled to San Antonio (1936) and Dallas (1937) for his ARC, and only, sessions.
Subsequently, the early Delta blues (as well as other genres) were extensively recorded by Alan Lomax, who criss-crossed the Southern US recording music played and sung by ordinary people. His recordings number in the thousands, and now reside in the Smithsonian Institution. According to Dixon & Godrich (1981) and Leadbitter & Slaven (1968), Alan Lomax and the Library of Congress researchers did not record any Delta bluesmen (or women) prior to 1941, when he recorded Son House & Willie Brown near Lake Cormorant, Mississippi, and Muddy Waters at Stovall, Mississippi.
