Check out Agalloch - Pale Folklore as well, not exactly Black Metal, but definately draws a lot of black metal influences (Ulver and Emperor to be specific).
According to your tastes, you'd probably love either of symphonic black releases:
Asmodeus - Phalanx Inferna
Thyrane - The Spirit Of Rebellion
Covenant - In Times Before The Light
Lord Kaos - Thorns Of Impurity
Capre Tenebrum - Majestic Nothingness
Troll - Drep De Kristne
