This is probably going to be my favourite Ayreon album along with 01, and that's saying something amongst all the great Ayreon stuff. The concept here is a bit more "down to earth" than usual - basically an interesting tale about a young mathematical genius and the people surrounding him, ending in an intriguing touch of mystery. The vocalists Arjen has used are ALL amazing - and we've got people like Marco Hietala and Tommy Karevic. And an array of incredible musicians. Choosing the right people for projects like this is half the skill. It's beautifully put together, the music perfectly complementing the vocal sections and the story. Prog at its finest. Emotional and intelligent, melodic and powerful. It's not an "easy" listen, not for background music - you need to pay it the courtesy of attention, take time to sit and allow yourself to be drawn into the story and properly hear the voices of the characters and the magical music drawing pictures around them. It's a holistic experience in music and lyrical imagery. And as always with Arjen's work, a beautiful package with lovely atmospheric artwork.
