Q:Information:  - Doom metal is an extreme style of heavy metal music that typically uses slower tempos, low-tuned guitars and a much "thicker" or "heavier" sound than other metal genres. Both the music and the lyrics intend to evoke a sense of despair, dread, and impending doom. The genre is strongly influenced by the early work of Black Sabbath, who formed a prototype for doom metal with songs such as "Black Sabbath", "Children of the Grave", "Electric Funeral" and "Into the Void". During the first half of the 1980s, a number of bands from England (Pagan Altar, Witchfinder General), the United States (Pentagram, Saint Vitus, Trouble) and Sweden (Candlemass, Count Raven) defined doom metal as a distinct genre.  - The euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain.
