Ayreon is a musical project by Dutch songwriter, singer, multi-instrumentalist musician and record producer Arjen Anthony Lucassen. Ayreon's music is described as progressive metal and progressive rock sometimes combined with genres such as folk, power metal, classical and electronica. The majority of Ayreon's albums are dubbed "rock operas" (or "metal operas") because the albums contain complex storylines featuring a host of characters, usually with each one being represented by a unique vocalist.
