I've recently read "Stairway To Heaven"-Led Zeppelin by Richard Cole.
And today I've bought "Hammer of the GoRAB"-Led Zeppelin by........Well I forgot the name!!!
Let me put it this way, if you like reading about drugs. Read Anthony Kiedi's Scar Tissue. Personally I loved it, read it cover to cover like 20 times. Couldn't get enough of it.
