‘Blues and jazz’ explores the connection between blues and jazz. Both blues and jazz have been closely intertwined since their inception — when jazz became nationally successful New Orleans blues was the main repertoire. In the 1940s and 1950s jazz was split into two camps — those that favoured the New Orleans style, and those that preferred a more modernist sound. Ray Charles successfully tapped into both the jazz and blues audiences. Given this shared history, it would be better to discuss blues and jazz as one tradition marketed in different ways, rather than as two separate forms.
