Ayreon ( pronunciation (help·info)) is a project by Dutch composer and musician Arjen Anthony Lucassen. Ayreon's musical style derives mostly from heavy metal and progressive rock, but combines them with genres like folk, classical and electronica. The majority of Ayreon's albums are dubbed "rock operas" because the albums contain complex storylines featuring a host of characters, each represented by a unique vocalist.
Ayreon's music is characterized by the use of traditional instruments in rock music (guitars, bass guitar, drums, synthesizers, electric organs) mixed with instruments more native to folk and classical music (i.e. mandolins, violins, violas, celli, flutes, sitars and didgeridoo). Lucassen writes the music and the lyrics, sings and plays instruments on all of the Ayreon albums, alongside many guest musicians, but the drums are played by Ed Warby most of the time, so he is considered as a member, even though he's not an official one. Arjen has said he will keep making Ayreon music until the day he loses love for music or until the day he dies. Also, when asked on the "Ask Arjen Anything" channel of communication if there will be another Ayreon album, he simply stated "Definitely".
