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

The birth of rock and roll has produced many arguments. Peterson's production of culture perspective has weaknesses and strenghts. One of the strengths being that he analyses six factors that have brought around something new. He looks at the socio-economic platform for bringing about something new being Rock and Roll. He states that those artists in the 50's did not create the rock boom, they were just opportunists taking music that was already there produced by black artists putting the myths such as Elvis creating Rock and roll to sleep.

Peterson's theory is very useful in looking at the birth of Rock as it asks us to look at the original roots of the music such as thoses black artists from the 40's, e.g Wynonie Harris with Good Rockin Tonight from 1947. I think this theory asks us to look to cultural roots and artefacts of this music. Artists such as Elvis just developed the genre.

However the theory does not justify the birth of Rock and Roll and give us a definitive answer as to where the exact birth of Rock and Roll came from.
