The cover pretty much explains it all. With out a doubt this is the most comprehensive coverage you will get. They practically have the lot from obscure singles and albums to The Beatles,Who.Camel etc. I am surprised that no one has posted this book.
The reviews on the more obscure albums in the book are more inclined to be leaning towards the accoustic side of Psyhedelic and prog but that seems to be the authors preference. Most I agree with but once again that is my taste in music and other people will have a different view.
This is an essential book for me and I recommend this as the best I've seen.
I wish there was one for the States as well as the rest of the world. As i would be buying them.
One other note there was an earlier edition but not as much in it.
