To Be honest I love the 60s and 70s, but hate the big egos and the cheese of the 80s... For the 80 i like to remember the more experimental stuff, as for the nineties, well, there's just too much music for me to recall ( i think that's when the whole music buisness kicked off)...
I'm glad that some poeple really enjoy playing guitar, but does it really need preserving? It's on record!! It's on audio, vidoe and how to play [fill in the blanks] book...
Personally I like to further the "sound"...
Well that's just my humble oppinion...
