We defiantly had many Punk movements in the Early 80's. First it seemed the Oi' or Nazi-Punk movement was gaining a lot of momentum but it was quickly rejected. Many bands rejected this movement including Crass on their "Noise not Music" tour which I attended. The Olympic Auditorium melee was a directly related to the large number of Nazi-Punks in attendance. This movement went underground shortly after and became the more popular White Power movement that swept the LA region. This group was trouble they created some very violent gangs that started with FFF (Fight For Freedom) after a violent shootout among their members the group broke off into two groups. One group FFF was the less violent Anarchist movement and a more violent off-shoot was then formed called The L.A.D.S.
The LADS or (LA Death Squad) were a feared Oi group that had roamed the LA streets causing random acts of violence. These two gangs spurred an anti-Nazi punk movement which causing a backlash, only the most fervent members remained and the Nazi-punk movement died around 1991.
After the late 70's now into the early 80's The Clash, Sex Pistols and New York dolls were being rejected for more aggressive music. The birth of early 80's punk was now formed with, The Exploited, The Dead Kennedy's CRASS, Black Flag, GBH, Fear and the Germs. The movement really gained mass appeal when small movie called "The decline of western civilisation" was released. After this movie punk really took off and hit probably the peak in USA around 1984-1985.
The movement remained non-violent until around 1985 when I stated noticing punk gangs appear. Skin heads were everywhere and punk gigs became more and more violent. As more and more gangs attended gigs I quite going to them. The slam pits became dangerous and fighting was the norm instead of the extreme. Early on fighting was considered fighting against your brothers but later younger and younger punks with something to prove became the norm.
I then started to attend smaller more nitch punk groups, like Seven Seconds, The Dickies and Agent Orange and met Kevin Seconds on more than a few occasions. At about this same time Skate punk was becoming popular and punk was starting to be aired on mainstream radio, the kiss of death for punk music. Punk can not survive in the mainstream, the movement is design to be underground and not intended for mainstream audiences. In all honesty without the Fad movement behind punk most escape to another Fad that is not exposed. At that time the other Fads were Mod (The Jam, The Lambrettas, Secret Affair), Ska (Madness, The Specials, The Selector and The English Beat), New Romantic (Roman Holiday, Duran Duran, Adam Ant) , Gloom ( Alien Sex Fiend, Specimen, Tupelo Chain Sex and Christian Death).
I had many friends in all scenes, I was a Mod, so of course I had lots of Mod friends but to improve the Mod numbers to compete with Punk, The Mod-Ska movement was then intertwined into one group. Shortly after 1985 most of these Fads died because of mainstream popularity. I stopped listening to all forms of underground music soon after that because everything got too aggressive and violent.
The modern youth of today in an ever increasing attempt to show up his parents has brought most of the modern underground movements to violent ends. Most smart youth will not enter into underground movements for fear of violence, they will typically listen to the music from a topically, this allows for bands to sell albums but the movement suffers as a whole. It is my belief that the best years are behind underground movements, the 1980's were the pinnacle. You will now receive pre-packaged establishment cookie cutter tailored punk/ska music from bands like No Doubt, Green Day and Rancid.
