I'm pretty sure COB is from finland.Never heard of scandanavian death metal,but black of course.I know immortal used their cold surroundings for inspiration.I think sweden is best known for its death metal.Why some of the greatest bands came out of florida is beyond me...I lived in palm beach gardens and any kind of music scene was non-existant.Mabey up in tampa its better...
Anyway...yeah,geological differences are often used in association with different styles.
Later! \m/
