Euro-Rock has a different sensibility than either North American or British rock. Most Euro-Rock sounds as if Chuck Berry didn't exist and that the Beatles never registered before Sgt. Pepper. It is arty, moody, fantastical, and symphonic, drawing more from classical and European folk than the blues. That is part of the reason why Euro-Rock was rarely heard outside of Europe, but the other reason is that the music was insular, rarely inviting outsiders to become accustomed with their traditions. In fact, Euro-Rock was often overshadowed in terms of popularity by Euro-Pop and Euro-Dance, as well as British and American rockers. Nevertheless, it retained a fanatical following within Europe, particularly among art rockers.
