Glam rock is a subgenre of rock music that developed in the United Kingdom in the early 1970s and was primarily defined by the hairstyles, makeup, and flamboyant clothing of its musicians, particularly platform shoes and glitter. Glam artists drew on diverse sources, ranging from bubblegum pop and 1950s rock and roll to cabaret, science fiction, and complex art rock. The flamboyant clothing and visual styles of performers were often camp or androgynous and have been described as playing with other gender roles.
