The 1970s rock genre known as Glam was characterized by its outrageous costumes, theatrical performances, and catchy pop-rock music. It was a popular style of rock music in the United Kingdom during the early 1970s, and was heavily influenced by the glam rock movement of the 1960s. Glam rock bands such as T. Rex, Sweet, and Slade were some of the most successful acts of the era. Glam rock was also known for its androgynous look, with male performers often wearing makeup and female performers wearing masculine clothing.
