Coming out of the neo-classical, theatric, fantasy-oriented school of prog metal is Rhapsody.
Their style, while definitely way over the top, is rather above and beyond a lot of their ilk due to quite authentic classical/operatic elements.
These elements include orchestral sections and choir-type vocal portions.
Their brand of metal is certainly not lacking, though, with great intricacy, speed, and skill.
The arrangements are very well done.
If fantasy-oriented prog metal is your flavor, then this album is for you.
It is one of the best of that style.
