Don't wear a shirt if you don't want to or better yet show us your chest hair...
Nothing says relaxation than long hair and air flowing through your flare...
Johnny Rotten once said that everyone looked like teddy bears in the 1970's...must have been referring to those ugly knits:
:P Blech!
Aside from all that wretched taste in fashion, there was a top 40 music and radio industry which dominated the air waves. It thrived off pop music and very long rock songs. By long songs I mean the tireless sound-waves of soft rock, country rock, southern rock, art rock, prog rock, glam rock, hell even metal. Although disco wasn't Rock, that too was weak, that and the 1970's Pop was highly wretched with empty messages. Not all of it was bad, but it was overwhelming awful. The point is that mostly mainstream sounds sucked. FM Radio was supposed to be a blessing! Not a dreaded curse!
Rock music had long solos that went on and on and on. It became excessive due to the use of the stadium; reaping the heavy rewards of an arena. How big do you need a stage to perform? So unnecessary because it's just another way to make even more cash.
Rock 'N' Roll is not about selling out a venue. It should NEVER be an opera. This excessive culture would extend itself to its height in even higher in the 1980's.
Not an expert on the 1970's, but just look at the pictures and they practically give it all away. The idea of the 1970's was to relax. Relax to forget your problems because it feels so damn good. Why bother working so hard to change the world when its easier to join in, conform, or not do anything at all. It was a hedonistic society. This mentality simply made society full of lazy, sluggish, and temporarily happy citizens.
For ten long years, a generation was being denied the innovative music that it deserved. Hence Punk became the new innovative form of Rock, that was intended to fight the record companies and destroy the pop crap once and for all. Punk Rock was the atomic bomb to be dropped on mainstream culture and social issues. Enough was enough. No more corruption from the government and no more superficial/shallow pop culture designed by the corporate oligarchies of the world. Punk was to re-instill in the energy lost in Rock music because it became so damn LAZY and overbloated.
