This album is perfect. As far as review criticisms, you used "epic" a little too much in the opening of the second paragraph. In fact, it's said too much in general. Once should be enough.
And if you don't want to die from fan brutality, avoid saying that they could beat out Sigur Ros.
Overall, decent review.
The passion you felt when you listened to this album definitely bled through the words. However, that is NOT a bad trait of your review, In fact, showing excitement and enthusiasm of your opinion is what makes it believable and makes it human.
Because what is music again? oh yeah, It is an expression of self. Why shouldn't writing be just as expressive music.... wait.... yes it is.
