Punk is not a music genre as in it's true form it is played by people who can't play, The Slits being the perfect example. For me '81 was a transitional time hearing In A Car, Jellybeans, Complete Disorder and The 1st Peni ep. I have been playing music for 33 years and still have no idea how to play a scale or what key I'm playing in.
I'm not doubting your statement and actually agree with a big portion of it, but can you explain why you chose some of THE most proficient musicians in punk as your follow up to saying you like music played by people that can't play? Or were you saying those are examples of punks that can play? Peni ep is incredibly well played, Disorder guitar player could clearly play guitar, Meat Puppets might have been amateurs but they were writing some complicated stuff, and 1/2 of the jellybeans comp is like, some of the best musicians in punk (bad brains, black flag, DK, etc).
To my 14 year old ears all of that stuff just sounded crazy. Whether it was played well was of no importance and I wouldn't have had a clue anyway. I love loads of stuff that is played very badly that I probably would have shunned had I been old enough to know any different. I was more going for the anti-genre, anti rockist slant. Anyway, I don't think Blinko could play well at all and I think Disorder would be horrified to be called any thing close to proficient.
