...ok....In my view
...the Golden age of Rock-n-Roll was 1952-1962.
.. the Platinium age of Rock-n-Roll was 1963 - 1973
.. the Silver age of Rock-n-Roll 1974-1984.
Since then... most everything has been lame...weak , or has been done before....(except Nirvana..and a few other rare exceptions)..IMHO
