What is the author's style in Mystery Train: Images of America in Rock 'n' Roll Music by Greil Marcus?

Marcus' reason for writing this analysis of rock 'n' roll music appears to be an attempt to define American culture as it is portrayed in the lyrics of early rock 'n' roll music. Marcus also discusses the ways in which American culture has changed in response to this new form of music. He deals with artists, those who are not afraid to speak their mind through their music, even if it means offending or shocking their audience. Marcus also describes the way these audiences impact the songs and sounds that each artist creates.
