This book presents a complete history of rock and roll music from its earliest days to the present. Rock and roll traces its roots to the music of the early 20th century. Its infectious sound, characterized by catchy guitar rhythms, a strong beat, and youthful lyrics, sparked a musical revolution beloved by the young and initially scorned by many adults. The emergence of rock and roll signaled a monumental change in popular music, and as rock grew, it assimilated a vast range of influences, including country, folk, jazz, gospel, and international styles, to become one of the most dynamic musical genres of contemporary times. "American Popular Music: Rock and Roll" explores the history of this musical genre as it took the United States by storm.
