Blood in Our Wells has almost 'progressive' elements (basically just more varied song structures) and some people refer to it as 'cinematic' because it includes samples from some Ukrainian (or Russian, can't remember) movie. The sound production is more full and professional but not too polished or anything. About Ukrainian folk influences, yeah there's certainly more of that, since Forgotten Legends and Autumn Aurora were basically just beautiful nature albums, couldn't sense those albums as so 'Ukrainian'. Since The Swan Road they've definitely added hints of their home country to the music.
I just realized I own 4 different versions of BioW release: original cd, super jewel box cd, original vinyl, and picture-LP. What a fanboy! And it's definitely not the only Drudkh album of which I have many versions, not going to even list them here
