I love 'Puritanical Euphoric Misanthropia', and I definitely recommend 'Eonian'. 'Eonian is a lot slower, more mid-paced with choirs and things like that, and some of the old school metal fraternity don't rate it, but I think it's actually really enjoyable, especially after a few listens.
You might also like 'Death Cult Armageddon', which is the follow-up to 'PEM' and fairly close in style (although shitter). Personally I prefer the two before it, 'Spiritual Black Dimensions' and 'Enthrone Darkness Triumphant', so check them out for sure.
NP: Running Wild - 'Blazon Stone'
My first Running Wild album, courtesy of True Belief, and I'm really enjoying it. Great riffs here with an infectious 1991 metal atmosphere.
