A) Music movement started in the 70's with multiple reasons and causes. There was an Americn and British Punk movement. Proto-punk bands such as Iggy Pop and the Stooges , the Motor City 5, and the Velvet Underground were influential in setting the stage for taking the risks bands like The Ramones, The Dictators , The New York Dolls, and Blondie did.The British movement supposedly was started by one of the following: The ecnomic disaster that occured in the mid seventies, and the youth's lack of patience with the british government. A movement made out of boredom by Johnny Rotten , lead singer of the Sex Pistols.This Movement caused the creation for most genres of music today, it's even represented in the roots of such types as hip hop, rap, pop, modern rock, goth, electro, two-tone . It did not create these genres, but it certainly kicked down the door for them.B) Culture started in the 70's by the same music movement. The point of the culture was like the music, be yourself and disregard the angry emotions it may stir up. No longer a real culture, only a burned image with the values behind it lost, you can see it in stores such as Hot Topic. People No longer understand it was always about being yourself and not being anyone's shadow.C) Modern Movement, characterized by some bands that have actually kept the movement alive, some by giving off the image, and pop-punk bands that are, regardless of what people want to say, in way of the Ramones and even the Misfits. Pop Punk is a very melodic form of punk, it's not " pop" because it's popular, it's pop because of the style of playing. Bands that try to sell an image alone with no true love for the music are the ones made fun of the most, with little or no time together before being popularized by mainstream tv. These are the same bands that promote a pre-made image that's ready to sell to a pre-teen to early adult demographic. For the most part it works, and this entire culture has been reffered to as " Mallcore " or " mallxcore ," because these are the same people that have never heard of the Ramones or Sex Pistols but think they're punk because they shop at hot topic and listen to MTV's Flavor of the week " band." feel free to laugh at these people, most people who know what the music is about do.The Current culture is in a sad state because it's focused on replicating the 70's instead of being itself. There are a few who understand it and refuse to subscribe to the image mold.D) Music Structure. Many like to characterize this genre with Power chords only and simple drum beats. These People are complete and utter idiots and should be regarded as imbecils. They more than likely know nothing about music in the first place, or are just that type of idiot that doesn't understand other types of music can be good, and that music, like other things, is all about opinion. Punk has had it's fair share of complicated guitar solos, insane drumming performances, all while keeping a melody, which most " jam bands " sorely lack, along with talent and lyrical prowess. Many of the early punk bands did utilize simple chords and beats, but like all types of music, it branched out and has many styles, from simple to complex, traditional to exotic, it all has to do with where you're looking.
