Easily their best work by far. Like words cannot do justice to the absolute god-like guitar playing and singing and everything else, songs like fly to the rainbow and we'll burn the sky never fail to put me in absolute awe with their mind boggling solos and riffs that are just pure ecstasy, again no justice can be done to accurately depict the magic these songs are. Other fantastic songs are polar nights which has a hypnotic intro that is quite frankly amazing. The tone and everything about how the guitars sound is amazing and the solos are beyond perfect, klaus's singing is beyond astonishing. I wish I can give it more stars it is that good
