Query: Masters of Metal

This book is amazing. It's got everything you would need to know about Metallica. My only problem is that it was written in just after the Black Album, so if you're looking for recent info, you may want a different book. However, if this doesnt matter or you are a collector of anything by Metallica or about Metallica, you need this book. It covers all of the history of the band, from when they played the Whiskey in San Francisco to the release of the Black Album. It also covers the tours Metallica has appeared on or headlined. The book has around 50 pictures as well. I strongly reccomend this book to anyone looking for information on the greatest band of all time.
