The other day I read a thread (can’t find it now, sorry) about someone who was missing out on 80s metal. Then I noticed the thread about Eddie Trunk’s list of the best metal bands of all time.
For those who are interested or have questions, MAP OF METAL will take you through the history and play some examples…enjoy. 
Cool. I wish there was a way to zoom out though.
I hate you. I’ve now found a new genera of music I have to check out. I’m really digging the Medieval Metal.
I am pleased to see Visual Kei acknowledged - I’m not a fan of it, but most people go ICKY ICKY ICKY and run away.
Personally, I spend my time travelling between the great lands of Symphonic Metal and Melodic Power Metal with occasional visits across the sea to Goth Metal.
