Janne,
Great that you put Solaria on the lead! The song is very atmospheric and Kevin does a great job on the backing vocals!
A couple of small nits:
I partially agree with Ray about the voice getting a little bit "sharp" in the choruses. It didn't bother me that much, though.
On the other hand, in the verses Solaria could probably be mixed in a little bit hotter.
I have to say, I didn't so much like the cut offs of her voice here and there. But I believe you explained why this was necessary.
All in all definitely a worthwhile listen.
Rob
