Dreamspace is by far the best record. It's the darkest, the heaviest and the all-around-awesomest record that they have ever done, with Shattered, Abyss, Tears of Ice and Eyes of the World being standout tracks, along with the title track (and Full Moon, the Japanese bonus track).
And holy fuck. I've been waiting for this live release for ages, ever since it was known that a live DVD would exist. That setlist is fucking killer.
