That's a little extreme. It's most definitely not the best album ever made.
It is, however, a very good Borknagar album. Finally they do something that has more than one decent song on it. And yes, I'm talking about Quintessence as well.
Vortex has done a great job and seems to have lived up to his name, because for over a decade he has put the "meh" in metal. It looks like he got off his ass and stopped letting all his fanboys fellate him for putting out mediocre bullshit and actually did something nice. Well done.
