The Red in the Sky is Ours maybe? It contains riff patterns like no other album, and was the first music I heard that required the sort of attention that made one want to write their own, if for nothing else, then to gain a more insight into the album.
As for recent stuff, maybe Lord Wind will spark the start of a genre in the same way that Sol Invictus/Death in June did. There's a simple uniqueness in the last two Lord Wind releases, and I think a lot of room for alteration and some improvement.
