I've lived in the bay area for quite a long time. I saw more metal/punk/thrash/art shows on the peninsula and east bay than most people ever got to even go out. So you'd think I'd defend this movie, but the commenters calling out SLAYER and SACRED REICH and more are spot on... metal has little to do with the bay area. The bands here weren't icons or more artistic or innovative or pioneering, they just had more opportunities to earn recording careers with better marketing here on the doorstep of Bill Graham Presents, Empire, Hyde Street, etc. SF has always had great music, but claiming this area "gave rise to many mavericks of metal" is a huge stretch.

Sorry, but the real ranking of the greatest thrash metal albums is: • Slayer – Live Undead (1984) • Sacred Reich – Ignorance (1987) • Sepultura – Beneath the Remains (1989). Learn this by heart.

After Slayer's Hell Awaits Exodus' Bonded By Blood is the greatest Thrash album of all time. Third is Poison's into The Abyss. Deal with it.
