How useful is a production of cultural perspectives in understanding the birth of Rock n Roll?

As Rock and Roll music is based around the huge social changes of the 1950s, I think it is highly useful to observe the birth of rock music from a cultural perspective. Rock and Roll was generated by culture, but I also believe that the music was created by not one cultural element but several which all contributed in the development of this legendary music which has existed for 60+ years. The social changes of the era play a key part as it was the beginning of the teenage/rebel era and I think this cultural element helped spark the popularity of the music. The famous artists themselves have a huge amount of responsibility for the birth of the music, but I would also agree that most of the key artists, such as The Ravens, were generally formed from an African American cultural background, and I believe much of the blues rhythm that was created comes from African American bands. So I believe that all these factors  were key during the era, to the birth of Rock n Roll.
