I have been listening to rock songs for a couple of years now. I read several wiki articles, lyrics interpretation sites and so on. I have so many questions in my mind like:
The 'inheritance' relation between different genres e.g 'Sabbath Bloody Sabbath', as per wiki, is classified as heavy metal which in turn is rooted in psychedelic rock
While I understand that only after years of dedicated listening, one can classify a song into a genre, I would really like to understand the logic behind establishing a song's genre by listening to it
What I am searching for is 'reliable'(??? - widely accepted/written by proven rock artists/connoisseurs?) material - documentaries, books and so on which track the origins and developments of the rock movement/era.
