Tired of German techno? Try some Swedish metal. That is the message of Volvo's new U.S. outdoor advertising campaign.The campaign has attracted a great deal of attention via social media sites such as Facebook and Twitter, where one person called it "the best car ad in history." "We have noticed [all the attention the ad has attracted] even here in Sweden and it's pretty funny, Volvo's press officer Bo Larsen told Dagens Media. Sweden Rock Magazine, Scandinavia's biggest hard rock magazine and Sweden's top-selling music magazine, recently celebrated issue #100 by naming the 100 greatest Swedish bands of all time. "Over the past couple of decades, it's hard to think of another country with a population equivalent to that of New York that's had such an impact on hard rock and metal as Sweden has," said Sweden Rock Magazine editor-in-chief Martin Carlsson.
