Yeah man, I could listen to The Book of Souls all day.
So far, the only track I've heard from Opeth's newest album is "Will O The Wisp," and I like that one. I didn't care much for Heritage at all, but I thought Pale Communion was solid, and I like pretty much everything else they've ever done. They've fully embraced the prog rock thing, and I'm fine with that. They're still the same band as far as I'm concerned. I was listening to Blackwater Park again at some point over the summer, and I can totally see how they got from there to where they're at now.
I really like Delain. They have become a solid little band that has only improved with time. There isn't much intricacy to their guitar work, but that doesn't bother me at all. I've listened to Moonbathers a few times now, and I think it's their best album yet, which I also said about their last album. It took me a while to realize this, but what stands out for me with this one is actually the improved orchestral/keyboard work and the lyrics in songs like "Turn the Lights Out." They're surprisingly deep, for Delain, anyway.
I listened to a few minutes of Gallowbraid, and they sound a lot like Agalloch, who have sadly split up. I'll have to sit down and check 'em out. Not sure which Nightwish vocalist/era you prefer if any, but I thought their newest album was absolutely amazing. There are so many good songs on it, but "The Greatest Show on Earth" is probably the best symphonic metal song I have ever heard.
