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

According to Peterson there are 6 factors for the emergence of Rock and Roll, which are law, technology, industry structure, organization structure, occupational career and market, yet these don’t necessarily give a proper understanding of why Rock and Roll music can be classified as Rock and Roll music as Peterson doesn’t go into great detail about the actual music content. Though Peterson does state “these are times when the usual routinising inhibitions to innovate do not operate as systematically, allowing opportunities for innovator to immerge” which shows that he does explain how social and historical contexts affect how the music is made and how it changes over time. This emphasizing on the fact that even today people cannot decide which song was the first Rock and Roll track, whether it was Elvis Presley with That’s all right in 1954 or The Andrew’s Sisters with Boogie Woogie Bugle Boy in 1940.
