My god this is a beast of an album. It is a never-ending satisfying piece of wholesome solemn ultra calming music. You will not finish this album in one sitting; you will fall to sleep. Which is why you should listen to it in parts to get the full feeling for this.
This is practically impossible to listen in one sitting. The 7 hour opus is Rich's version of a dream. Somnium translated from Latin literally means "dream", which is why the concept of this album needs to be touched on. The sounds of water droplets, storm showers, waves of water all signal calmness and peace. While the album itself is overbearing in its track time, its vision may be its greatest strength.
