Alice Cooper in the context of "Heavy metal music"

Hard rock or heavy rock is a heavier subgenre of rock music typified by aggressive vocals and distorted electric guitars. Hard rock began in the mid-1960s with the garage, psychedelic and blues rock movements. Some of the earliest hard rock music was produced by the Kinks, the Who, the Beatles, the Rolling Stones, Cream, Vanilla Fudge, and the Jimi Hendrix Experience. In the late 1960s, bands such as Blue Cheer, the Jeff Beck Group, Iron Butterfly, Led Zeppelin, Creedence Clearwater Revival, Golden Earring, Steppenwolf, Grand Funk Railroad, Free, and Deep Purple also produced hard rock.

The genre developed into a major form of popular music in the 1970s, with the Who, Led Zeppelin and Deep Purple being joined by Black Sabbath, Alice Cooper, Aerosmith, Kiss, Queen, AC/DC, Thin Lizzy and Van Halen. During the 1980s, some hard rock bands moved away from their hard rock roots and more towards pop rock. Established bands made a comeback in the mid-1980s and hard rock reached a commercial peak in the 1980s with glam metal bands such as Mötley Crüe, Bon Jovi and Def Leppard as well as the rawer sounds of Guns N' Roses which followed with great success in the later part of that decade.

Glam rock (also known as glitter 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.

The UK charts were inundated with glam rock acts from 1971 to 1975. The March 1971 appearance of T. Rex frontman Marc Bolan on the BBC's music show Top of the Pops—performing "Hot Love"—wearing glitter and satins, is often cited as the beginning of the movement. Other British glam rock artists included David Bowie, Mott the Hoople, Sweet, Slade, Mud, Roxy Music, Alvin Stardust, Wizzard and Gary Glitter. In the United States, the scene was much less prevalent, but US artists such as New York Dolls, Sparks, Suzi Quatro, Iggy Pop, Alice Cooper, Lou Reed and Jobriath achieved success in the UK and/or US. Glam rock declined after the mid-1970s, but influenced other musical genres including punk rock, post-punk, gothic rock and glam metal. The new romantic movement, which began as an underground fashion subculture movement in nightclubs in the late 1970s before becoming mainstream in the early 1980s, was also inspired by the visuals of the glam rock era.

The New York Dolls were an American rock band formed in New York City in 1971, who released two albums, New York Dolls (1973) and Too Much Too Soon (1974), before disbanding in 1976. Its classic lineup consisted of vocalist David Johansen, guitarist Johnny Thunders, bassist Arthur Kane, guitarist and pianist Sylvain Sylvain, and drummer Jerry Nolan; the latter two had replaced Rick Rivets and Billy Murcia, respectively, in 1972. In their appearance, they drew from drag fashion, wearing high heels, hats, satin, makeup, spandex, and dresses.

In 2004, the New York Dolls reunited with a new lineup and later released three more albums. After a British tour with Alice Cooper in 2011, the Dolls disbanded again. By 2025, all original members of the New York Dolls had died: drummer Billy Murcia (1951–1972), guitarist Johnny Thunders (1952–1991), drummer Jerry Nolan (1946–1992), bassist Arthur Kane (1949–2004), guitarist Sylvain Sylvain (1951–2021), and lead singer David Johansen (1950–2025).

Laurence Joseph Mullen Jr. (/ˈmʌlən/; born 31 October 1961) is an Irish musician, best known as the drummer and co-founder of the rock band U2. A member of the band since its inception, he has recorded 15 studio albums with U2. Mullen's distinctive, almost military drumming style developed from his playing martial beats in childhood marching bands.

Mullen was born in Dublin, where he attended Mount Temple Comprehensive School. In 1976, he co-founded U2 after posting a message on the school's notice board in search of musicians. Mullen has worked on numerous side projects during his career. In 1990, he produced the Ireland national football team's song "Put 'Em Under Pressure" for the 1990 FIFA World Cup. In 1996, he worked with U2 bandmate Adam Clayton on a dance re-recording of the "Theme from Mission: Impossible". He has also collaborated with musicians such as Maria McKee, Nanci Griffith, Emmylou Harris, and Alice Cooper. Mullen has sporadically acted in films, most notably in Man on the Train (2011) and A Thousand Times Good Night (2013).
