Heavy metal as a genre has been concerned with nuclear warfare since the days of Black Sabbath. Their classics, "War Pigs" and "Electric Funeral", respectively, are among the first metal songs to describe war, political corruption and atomic holocaust. Iron Maiden's 1984 single "2 Minutes to Midnight", from their album "Powerslave", deals with the Doomsday Clock, while their later song "Brighter Than a Thousand Suns", from their 2006 album "A Matter of Life and Death", is primarily about the Manhattan Project. The theme continued in heavy metal through the early nineties, especially in the thrash metal subgenre. Metallica wrote many popular songs about nuclear war and political corruption such as "Fight Fire with Fire", "...And Justice For All", and "Blackened". Megadeth's name is taken from the term "megadeath," used to describe one million deaths from a nuclear weapon, and much of their album artworks and songs deal with nuclear war and weapons. Other thrash bands such as Sodom and Anthrax also wrote a number of songs on the topic. The genre even inspired bands like Nuclear Assault and Warbringer to adopt the subject in their band names themselves. This trend also spread to Eastern European metal with popular Russian metal band Aria writing the song "Last Sunset" (Последний).
