Hi there, so what i know is:
as détente broke down, progress on nuclear arms control stalled completely. As their relationship continued to erode, it became clear that both the U.S. and the Soviet Union had overestimated the extent to which détente would contribute to an agreeable and peaceful end of the Cold War.

Answer:
In the late 1940s, some white country musicians began to experiment with the rhythms of the blues, a decades-old musical genre of rural southern black people. This experimentation led to the creation of a new musical form known as rockabilly; by the 1950s, rockabilly had developed into rock and roll.
Rock and roll music celebrated themes such as young love and freedom from the oppression of middle-class society. It quickly grew in favor among American teens during the 1950s, thanks largely to the efforts of disc jockey Alan Freed. Freed named and popularized rock and roll by playing it on the radio in Cleveland—where he also organized the first rock and roll concert—and later in New York.
The theme of rebellion against authority, present in many rock and roll songs, appealed to teens. In 1954, rock group Bill Haley and His Comets provided youth with an anthem for their rebellion with the song ”Rock Around the Clock.” The song, used in the 1955 movie Blackboard Jungle about a white teacher at a troubled inner-city high school, seemed to be calling for teens to declare their independence from adult control.
Haley illustrated how white artists could take musical motifs from African American musicians and achieve mainstream success. Teen heartthrob Elvis Presley rose to stardom doing the same. Thus, besides encouraging a feeling of youthful rebellion, rock and roll also began to tear down color barriers in popular culture, as white youths sought out African American musicians such as Chuck Berry and Little Richard.
