You know what I love almost as much as the music John Darnielle makes with the Mountain Goats? His music writing. And, if you’re a regular visitor to his Last Plane to Jakarta blog, you know that one thing he loves more than just about anything else is metal (30 Short Poems About My Favorite Black Metal Band, anyone?).

That’s why I was so excited to initially hear that he would writing an installment for the always fun 33 1/3 book series on Black Sabbath’s classic Master of Reality. Not only is the book currently up for pre-sale on Amazon, for a limited time only if you email sabbathsampler@yahoo.com you’ll receive a ten page sampler of the book, which I highly recommend you do since there’s only about a .001% chance of this book being anything less than great.
