Rockin' Out offers a comprehensive social history of popular music in the United States that takes the reader from the invention of the phonograph to the promise of the Internet, from the heyday of Tin Pan Alley to the present day sounds of singer-songwriters, pop country crossovers, rock, and contemporary hip hop. It offers an analysis and critique of the music itself as well as how it is produced and marketed, including such recent phenomena as the rise of television idols, the introduction of reggaeton, and the return of protest music. 

Accessibly written, this text is organized chronologically and thematically around particular genres/styles of music and addresses such dimensions as race, class, gender, ethnicity, technology, copyright and the structure of the music industry as they affect the development of the music.
