How useful is a production of culture perspective in understanding the birth of rock and roll?

The perspective seems to ignore the music and more importantly the genres of music, therefore it might as well be called the birth of different forms of music rather than rock and roll. This apparent rock and roll of the 50s and the suggested rock and roll of Peterson's perspective incorporates Jazz, R&B, and black music, which in current times would be hiphop and so on rather than the general ideas of what makes up rock. The perspective suggests that the only reason rock and roll was born was due to the creation of vinyl, the distribution of music and the rebellion of radio. Peterson's six factors for the creation of rock and roll ignores the music and concentrates on the economic factors for example the industry structure with the different record companies. Peterson's perspective is key in understanding the economic and environmental factors but ignores the musicality of rock and roll.
