@kerzain: Liking the Giraffe Tongue Orchestra so far - thanks for pointing it out.
Re: Opeth, I've heard bits and pieces of their catalog but haven't really dug into them yet. I've added the new one to listen to in full, but of the singles they released, I liked Will o' the Wisp and was lukewarm about Sorceress and The Wilde Flowers.
Lots of other good stuff came out in the past couple of weeks, though. Here are a few of my favorites:
A single-song concept album about a band of Vikings sailing off into the winter seas in search of a rumored island out west of Ireland (spoiler: probably not a good idea). This might be my favorite thing Insomnium has done so far.
Epic proggy doom of the best kind. Amazed that these guys can take a 17-year hiatus from their last album and come back sounding so assured, and I'm definitely going to be checking out their back catalog now.
Ripping sci-fi tech-melodeath. Lots of fun.
Atmospheric Scottish folk/black metal, complete with bagpipes. I loved his previous album, Aura, and the preview track from the upcoming album is just as good.
