I recommend this book for anyone who wants an ideal perspective on applying the bass guitar to extreme metal. His techniques are incredibly efficient and his explanation of scales and intervals is easy to interpret and thus perfect for a beginner.
He includes a list of preferred scales, modes and patterns that are typical of the genre and it's respective sub-genres, so you can get a condensed, more conventional approach. The .mp3 files on the CD that correspond to the exercises in the book kick ass too. Any fan of Cannibal Corpse will undoubtedly love this book. You can even find some useful philosophy in there.
