A lot of good music here. I like your music taste OP.
My album suggestions is:
Caligula's Horse - Bloom Vocals can remind me of Karnivool at times. It's melodic groovy and beautiful, but also heavy at times.
Shining - Blackjazz a great and original band. I honestly don't know any band that sounds like them.
Ihsahn - Eremita. Ihsahn was the frontman of Emperor, but has moved over to the progressive side of music with his solo project.
Leprous - Bilateral and The Congregation. Another band that I think is very original. Has their own distinct sound. Could need a few runs before it sinks in, but when it does.. Prepare for awesome music.
This applies to most of these band really..
Borknagar - Urd. With a base in blackmetal they can be quite heavy at times, but they have a cool progressive twist to a lot of the never albums. And good clean vocals!! New album came out on friday/Saturday, haven't heard it yet, so can't recommend it
Solstafir - svartir sandar. This is really good. Started as blackmetal, but ended up as something completely else..(not blackmetal anymore) Worth a try!!
Susanne Sundfør - The silicone veil. Not gonna say much about her. She has the most wonderful female vocals I know, and with her catchy, but dark, jazz inspired pop... Just try it.
I'm gonna stop now, haha.
A lot of music here, hope you check some of them out! Please tell me if you happen to enjoy any of them. As I said earlier, a lot of these albums need some runs in the player before they sink in. Very complex a lot of this.
Enjoy!
