Twisted Sister

From Lastfm:

Twisted Sister is an American heavy metal band from New York City popularized in comedic music videos on the television channel MTV in the 1980s. Although formed by guitar player Jay Jay French in 1973, all of their songs were written by the lead singer Dee Snider. They fused the shock tactics of Alice Cooper and W.A.S.P., the rebellious mood of the New Wave of British Heavy Metal, the style of the New York Dolls, and the extravagant makeup of KISS. Often misconceived as glam - the makeup and Dee's especially was more transformed into a horror creation, and the music is a lot more hard hitting, with less lyrics about sex than glam rock.

The group's hit songs include "We're Not Gonna Take It" and "I Wanna Rock". Many of the band's hits theme around parent vs. child conflicts and criticisms against educational system. The group had a glam-like image but musically they were closer to classic heavy metal bands such as Judas Priest and Motörhead than the other glam metal/pop metal bands of the era, for example Mötley Crüe, Poison and Ratt.

Their hit song S.M.F. should also not be forgotten.(Sick Mother Fucker)

From Wikipedia:

Twisted Sister is an American heavy metal band from New York City. Their work fuses the shock tactics of Alice Cooper, the rebellious mood of the New Wave of British Heavy Metal, and the extravagant image of glam rock bands such as New York Dolls notably for the makeup. Musically, the band implements elements of traditional heavy metal bands such as Judas Priest, along with a style that is similar to early glam metal bands. The band is generally categorized as glam metal for their earlier work, although the band does not consider themselves to be so.

Although the band was formed by guitarist Jay Jay French in December 1972, all of their songs were written by Dee Snider from 1976 onward. Snider remarked to Johnny Carson that the proposed name for the band was "This" but was rejected for fear of fans saying "This sucks". He describes Twisted Sister as "Slade meets Sex Pistols". Twisted Sister's most well-known hits include "We're Not Gonna Take It" and "I Wanna Rock", both popularized in the USA by regular airplay on MTV in the 1980s. Many of the band's songs explore themes of parent vs. child conflicts and criticisms of the educational system.
