How would you describe rock and roll has changed through out the decades. Be specific. (3 sentences)

Rock and Roll is an attitude as well as a music genre. It started out as a new style of dance music aimed at teenagers in the 1950s and by the end of the 1960s it had transformed the American cultural and political landscape. A blend of African American and White musical traditions, Rock and Roll challenged existing social norms including the segregation of the races. It also became the soundtrack of a youthful generation defying the expectations of their parents.

Rock and Roll paved the way for the self-expression and free thought of the 1960s. It encouraged Americans to speak out on political issues, such as Civil Rights and the Vietnam War. It helped teens integrate in the 1950s and 1960s and opened the door for black artists to be played on mainstream radio and television. It influenced clothing, dance and language.

The roots of Rock and Roll go back to rhythm and blues and country music. Because rhythm and blues musicians were African-American and the music was considered suggestive, it was not generally accepted by white audiences.

The history of Rock and Roll includes (but is certainly not limited to) the stories of Elvis Presley, the Beatles and the Rolling Stones. Elvis made the new music popular with white America, notwithstanding its origins in the African American musical traditions. And just when it appeared that the new craze was about to die out in 1959, the “British Invasion” of bands inspired by the American Rock of the 1950s injected a new energy into Rock and ensured the music would endure.
