Manowar is an American heavy metal band from Auburn, New York, United States, formed in 1980. They are known for writing lyrics with an emphasis on the heavy metal genre itself, fantasy (particularly sword and sorcery) and mythological topics (particularly Norse mythology). Manowar's sound is loud and bombastic; in an interview for MTV in February 2007, bassist Joey DeMaio lamented that "these days, there's a real lack of big, epic metal that is drenched with crushing guitars and choirs and orchestras... so it's nice to be one of the few bands that's actually doing that." In 1984 the band was included in the Guinness Book of World Records for delivering the loudest performance, a record which they have since broken on 2 occasions. They also hold the world record for the longest heavy metal concert after playing for 5 hours and 1 minute in Bulgaria in 2008.
Although the band has never been a mainstream commercial success in the United States, they maintain a strong cult following there. In contrast, they are extremely popular in the heavy metal scene in Europe, Japan, Australia and South America. Dedicated fans are known and referred to by the band as "Metal Warriors", "Manowarriors" or "Immortals", and collectively their fans are known as the "Army of Immortals". The band has sold over 9 million albums.
