Another of my favorites is
Zombie Girl. They have an electro/industrial rock style, perfect for Halloween
Other songs by
Zombie Girl include:
Creepy Crawler
I Want It
Bleeder
Screams From The Cemetery-this is one of my favorites for creepy ambiance... no vocals, and, ironically, no screams, just subtle music accompanied by ambient sound effects you'd hear in a cemetery.
Witches in Bikinis have a sort of campy,old school Halloween style. Check out these songs:
Dear Dr. Frankenstein
Video Vixen Vampire
A Scary Kind Of Love
All Hallows Eve
Hold Me, My Little Ghostie
Horror Flick Chicks
