I’ve finally figured out who the man in the black trench coat is in Halloween 5 & 6.
GAAHL! Sporting the “Thorn” Necklace! 
Awesome
HA!
Gaahl is one twisted dude. GORGOROTH are true Black Metal kings. If you’re into Gaahl I HIGHLY suggest his solo (pre Gorgoroth days) project called TRELLDOM.
Also check out the documentary TRUE NORWEGIAN BLACK METAL. I personally prefer the first 3 Gorgoroth lp’s but Gaahl is a GREAT front man.
And he may just be the man in black!
Yea I know the band I just dont follow his music much. I know who he is and what they are all about though lol. I watched that doc. TRUE NORWEGIAN BLACK METAL awhile back.
Ah cool! the guy who shot the doc released a pretty cool compendium book to the film with many cool unreleased pics. Most of it focused on Gaahl.
