The world of heavy metal is a very diverse one, spanning from bluesy hard rock to bone-crushing death metal. The common thread is the constant quality of the guitarists involved, always looking to improve their precision and speed, which is why that songbook will give you plenty to sink your picks into. The old-school bands are there (Motorhead, Iron Maiden), and the young bands are here too (Children Of Bodom, Avenged Sevenfold), as well as the six-minute multisolos behemoth (Megadeth).
