Machine Head is probably my favorite band ever. And I have been following them very closely for about a decade and a half now, reading all the available interviews they had given, digging old news articles from their earlier periods, building up a ridiculously extensive collection of old magazine scans, live bootlegs, TV appearances and what not...
And maybe because of that, this book was a bit of a let down for me because it didn't provide anything that I didn't already know. In fact, a few times I actually felt I knew more than what was actually in the book.
Then again, I gave the book to my father, who's also a fan of rock and metal. He read it, loved it, and decided to look deeper into the band and now he blasts The Blackening and Burn My Eyes every now and then.
So, basically, how much you'll like this book – or if you need to purchase it – depends on how deep into the band you are. If you are relatively new to Machine Head and want to have one source of information about what they are about, well – this is it.
