How useful is a production of culture perspective in understanding the birth of Rock & Roll?

In 2004 Richard Peterson presented us with a theory on why he believed the Production of culture (‘symbolic elements of culture are shaped by the systems within which they are created, distributed, evaluated, taught, and preserved.’) lead to the birth of Rock n Roll. In this theory he claims disapproves myths such as Rock n Roll being a result of the baby boom and the development of the new teenager and Rock n Roll being born because of such stars as Elvis Presley. In this theory Peterson covers Six factors (Law, Technology, Industry Structure, Organisation Structure, Occupational career and the Market) in which he believes lead to the birth of Rock n Roll developing on each one creating somewhat of a time line. Still one major flaw in this theory is it fails to show why Rock n Roll was so successful, it merely shows that there was a lead up to a new kind of music but fails to show why Rock n Roll became and why that particular mix of music worked so well
