what are the strengths and weaknesses of Petersons production of culture perspective on the birth or rock and roll?

Petersons Production of Culture Perspective attempts to explain why rock n' roll broke through in 1955. He looked at culture, cultural symbols, and artefacts to find an understanding of social norms and practices that are accepted in society.
The strengths of this perspective can be seen when we learn about the six key factors he looks at; law, technology, industry structure, organisation structure, occupational structure and the market.
However, this perspective does have weaknesses, a major one being that the actual music isn't ever taken into account and the question surrounding why rock n' roll emerged in 1955 is never really answered. Also no human emotions or elements are taken into consideration, he says that people bought music because it was on the radio but doesn't consider it's significance to individuals. Although technology is looked at it is never considered when looking at the creation of music, eg microphones and amplifiers.
All in all the perspective is useful when understanding the music industry in the past, but does have it's weaknesses, and doesn't answer many questions.
