According to a publication by the Central Intelligence Agency, there are more heavy metal bands per 100,000 people in Scandinavia -- that's Norway, Sweden and Iceland -- than in anywhere else in the world, as this map illustrates.
Ole, Lars and Sven are in the dark red, there.
Notice at the Northernmost point there, on top, in the middle? That little red area is the island grouping of Svalbard. Svalbard is an unincorporated locale of about 2500 people, occupied by Norway. About 700 of those 2500 people are of either Russian or Ukrainian derivation, while most the rest are Norwegians.
The four main industries on Svalbard are coal mining, tourism, research, and rockin' like Dokken -- that's jammin' to balls-out metal riffs, squeezin' the whammy bar, howlin' at the moon like Ozzy before the second rehab stint, poundin' that double-bass drum, lickin' that bass guitar, etc. ...
You know, I catch that "Vikings" show on the history channel once in a while, and those dudes DO look a lot like 80s Metalheads.
Anyway, all this raises a larger question -- why is the CIA researching heavy metal bands?
