What about the Music?

While Peterson's production of culture perspective gives clarity to the context of the birth of rock with its analysis of the industry structure, occupational opportunities and legal issues, it also manages to overlooks several other key aspects essential to understanding the rise of rock and roll in the 1950s. Peterson discusses some technological advances that allowed for the rise of rock, looking mostly at delivery of music and not so much at recording or instruments, which was explored by Theberge. Peterson also fails to look at the music itself. 
He sets up a strong framework for how rock came to be but it could be applied to lots of other things as well. Why did rock become popular at all rather than some other genre? Why 1955? Peterson just doesn't quite answer these, although if taken along side Theberge and other analyses, it gives a much broader picture of both the how and why.
