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

Peterson's production of culture perspectives gives a good brief understanding to the birth of Rock n Roll, but does not create a clear structure or identify the reason for Rock n Roll. Many approaches have been suggested for example Peterson's 6 factors of the emergence of rock n roll, and the factor of  the artists themselves making rock n roll become what it is now. The emergence of rock n roll artist themselves creates a more realistic view of why rock n roll was born due to the result of baby boom. 
          Simply, perspectives in understanding the birth of rock n roll is not very useful for the fact it sets up the a wide frame work of understanding, which in hindsight could cover most genres. It does not cover many ideas which contribute to rock n rolls emergence, It fails to discuss why rock and roll was discovered in 1955 or the technology used withing rock n roll, it also fails to address rock n rolls audience. Therefore it is credible to suggest the 6 point structure fails to pin point the main contributions which gave birth to the rock n roll era 1955.
