If you're not familiar with this genre, here's what Wikipedia says about it:
Glam rock (also known as glitter rock) is a style of rock and pop music that developed in the United Kingdom in the early 1970s which was performed by singers and musicians who wore outrageous clothes, makeup, and hairstyles, particularly platform-soled boots and glitter. The flamboyant costumes and visual styles of glam performers were often camp or androgynous, and have been connected with new views of gender roles.
You probably can imagine how much fun we had ;-)
