Query: Pure black metal beauty

This is by far Emperor's greatest release and unfortunately looks to be there greatest ever. With Anthems to the Welkin At Dusk they succumbed to the 3rd generation black metal posers and sold out. But In The Nightside Eclipse is a true classic of black metal. The best thing about Emperor is their classic usage of keyboards to complement and not destroy the rest of the music. The compositions are so brilliant and beautiful that i'm not sure if it can be classified as black metal. Unfortunately, the musicianship is not the best as the band seems to have a little trouble staying together at times. The recording isn't the best either with some bass drum kicks sounding like a snappy pop instead of bass and depth. The only reason i give 4 stars is that the recording does not give justice to such an album. Still, In The Nightside Eclipse is a powerful work of black metal and should be heard by anyone intelligent enough to appreciate this style of black metal that has been lost.
