Ayreon is a musical project by Dutch composer, singer, multi-instrumentalist and producer Arjen Anthony Lucassen. Ayreon’s music is a mix of progressive rock, progressive metal and power metal. It is sometimes combined with genres such as folk, electronica, experimental and classical music. The majority of Ayreon’s albums are “rock operas” because the albums contain complete storylines (aka “concept albums”) featuring a host of characters, usually with each one being represented by a unique vocalist.
