1968: in that single year, MLK and RFK were assassinated, Chicago rioted, Nixon triumphed, and Tet exploded. The top music acts were the Beatles, the Doors, Otis Redding and Marvin Gaye. Man circled the Moon. From Civil Rights to Vietnam, from rock & roll to rocket science, 1968 stands out as a concentrated dose of everything we think of as the Sixties.
