The Big Bang
Rock and roll didn't emerge from nothing. It was the inevitable collision of Black American musical traditions with postwar restlessness and the electric guitar. Chuck Berry invented the rock guitar solo. Little Richard brought the fire. Elvis Presley brought it to white America's living rooms, for better and worse.
The 1950s established rock's fundamental tension: a Black art form filtered through white mainstream culture, commercially explosive and culturally dangerous. Buddy Holly showed that a band could write its own songs. Jerry Lee Lewis showed that rock could be genuinely unhinged. And the establishment, from parents to preachers to the FBI, showed that they were terrified of what this music represented.
By decade's end, rock and roll had been declared dead multiple times. It was just getting started.
