I'm fairly convinced that metal started and ended with Obtained Enslavement, no one with half as much talent as Heks ever touched this genre. It's unbelievable how good Witchcraft is, it's contrapuntally and harmonically rich masterpiece. As a compliment, I would say Heks either stole from classical masters, or actually studied music at the conservatory for years (and god bless him for writing in metal style). It's definitely one of the most contrapuntal albums in metal and even entire popular music. Hell, it's more contrapuntal than some classical music.
Hek's mastery of harmony combined with one of the greatest metal producer (Pytten), raw guitar tone and 90's symphonic textures is a marvel of our times, in all seriousness.
Metal will never reach this peak again.

Sad but true. I would like to chat with Heks. Unfortunately he's disappeared from the internet.
