It's been a while since I discovered a good atmospheric metal artist, but this one did it, kicked me to the stars and you just stop working for a moment, it's truly inspired by cosmos, I would say there is a lot of trash among the good ones, artists who try too hard but actually miss some essential points, this genre requires some creativity (in respect of experimental) and it's a spiritual genre, a point many artists fail by adding harsh vocals (a big exception might be Veldes, I don't know why, this might subjective, but to me it fits) to it which rather destroy the atmosphere than enhancing it. Another point is monotony, which actually is an integral of the spiritual one, spiritual music is monotone, it's not complex, but experimental music and those who try too hard fail this point.
