A fresh progressive take on what we might fear is a stagnant genre. Must say i love the sound of real trumpets and trombones. Keyboards cannot compete.
As for what direction you might try out next you should get a professional choir and orchestra to join your congregation. Behemoth - the satanist is a prime example of how you balance the two contradictory elements without sounding cheesy.
But whatever you try next just keep it organic. Keyboards sounds goofy and out of place.
Favorite track: Black Death.
