This album is a pretty incredible concept album. It comes in two versions: with and without vocals. The concept of descending deeper into the ocean is better implemented with the vocals, and when I listen to the instrumental versions I often yearn for the vocal melodies. However, since the album was originally written as an instrumental album, the instrumentation alone is still quite impressive.

4.0/5 - Very good album, but also very dense. The emotional journey is very good, and the vocal performance is amazing.
