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. Glam rock visuals peaked during the mid 1970s with artists including T. Rex, David Bowie, Roxy Music and Gary Glitter in the UK and New York Dolls, Lou Reed and Jobriath in the US.

Musically glam rock was very diverse, varying between the simple rock and roll revivalism of figures like Alvin Stardust to the complex art rock of Roxy Music, and can be seen as much as a fashion as a musical sub-genre. Visually it was a mesh of various styles, ranging from 1930s Hollywood glamour, through 1950s pin-up sex appeal, pre-war Cabaret theatrics, Victorian literary and symbolist styles, science fiction, to ancient and occult mysticism and mythology; manifesting itself in outrageous clothes, makeup, hairstyles, and platform-soled boots. Glam is most noted for its sexual and gender ambiguity and representations of androgyny, beside extensive use of theatrics. It was prefigured by the showmanship and gender identity manipulation of American acts such as The Cockettes and Alice Cooper, the latter of which combined glam with shock rock.

Gary Glitter (born Paul Francis Gadd on 8 May 1944) is an English former glam rock singer-songwriter and musician.

Glitter first came to prominence in the glam rock era of the early 1970s. He had a long solo UK chart run during the 1970s, with several hits including "Rock and Roll, Parts One and Two", "I Love You Love Me Love", "I'm the Leader of the Gang (I Am)" and "Hello, Hello, I'm Back Again". Between 1972 and 1995, Glitter had 26 hit singles which spent a total of 180 weeks in the UK Top 100; twelve of those reached the Top 10, with three charting at number 1. He continued to record in the 1980s and 1990s, with his 1984 song "Another Rock N' Roll Christmas" being one of the Top 30 Christmas hits of all time. He released seven studio albums, and at least^[specify] 15 greatest hits collections or live albums. In 1998, his recording of "Rock and Roll" was listed as one of the top 1,001 songs in music history. The mostly instrumental "Rock and Roll, Part 2" has been played as a popular cheering song at American sporting events for several decades.
