All the vocalists perform their parts very, very, very well and believable. All the singing is clean without growling with the exception of the Death. For the growling-haters, it's only about two minutes from the duration of one hour and thirty minutes. The music itself is at parts very complex sounding progressive rock with lots of synth, acoustic guitars and distorted guitars. Some of the songs are heavy, some are more ballad-like.
All musicians are very good choices to their roles.
Nothing on this double CD is bad or boring. I enjoy the whole ride from the very beginning to the very end, and then again and again. The only part that isn't so great on this rock opera is the storyteller voice's, parts. But those are a small part of a great album. If you are after some totally different, great musicianship, great guitar and synth solos and especially the best vocal appearances, you should definitely pick this one up.
