I'm not really big on black metal (although there are a few I like), but I'm with the Melodic Death Metal stuff from Sweden (Arch Enemy, In Flames, At the Gates, Dark Tranquillity, Opeth, Amon Amarth, Meshuggah).
People keep saying that Denmark has some great metal bands, but the purpose of this comic is how much heavy metal music is produced in continental Nordic Europe (Norway, Sweden, Denmark, Finland). Statistics (Not sure how recent they are) show these places: 1st: Norway. Full of satanic black metal. 2nd: Finland. More death metal than black metal. 3rd: Sweden. They like to pretend they're 2nd because they're more enthusiastic about their death metal than Finns are. 4th: Denmark. Compared to Norway, there is almost no heavy metal in Denmark.
