I would like to start this by saying that I wasnt alive in the seventies and I never got the chance to see the likes of The Pistols, The Clash or even The Ramones. This is simply my opinion.
I think that:
Punk is a loud, fast, often anti-establishment type of
music. It was influenced by and has influenced many different types of
music. It started in the seventies and was popularized by The Clash, Sex Pistols and the Ramones. Punk is not an image it is a belief and a lifestyle as well as a type of
music.
Since the end of the seventies it has become impossible to truly define becuase it gave birth to so many different forms of
music such as
indie,
goth, hardcore, emo, punk pop etc. Because of this a sort of "punk snobbery" has developed, were "true punks" look down upon others for not being around in that era.
Definately Punk: Sex Pistols, The Clash, Ramones
A little bit Punk: The
Jam, Blondie, Green Day
Not Punk: Avril Lavine, Good Charlotte, Elliot Minor
