Glam rock, also known as glitter rock, musical movement that began in Britain in the early 1970s and celebrated the spectacle of the rock star and concert. Often dappled with glitter, male musicians took the stage in women’s makeup and clothing, adopted theatrical personas, and mounted glamorous musical productions frequently characterized by space-age futurism. Self-glorifying and decadent, glam rock positioned itself as a backlash against the rock mainstream of the late 1960s; on the periphery of society and rock culture, glam rockers were, as critic Robert Palmer put it, “rebelling against the rebellion.” — Encyclopedia Brittanica
