There are a lot of wonderful songs, beautifully sung, on this CD. Unfortunately, it suffers from what I call coarse-grain temporal dynamic range compression. It's basically wide-range normalization. It's not immediately annoying like the fine-grain dynamic range compression, which literally hurts my brain, but is still annoying in that it makes the songs unsatisfying as a whole. Track 12, for example, is supposed to start very soft and get extremely powerful as it reaches climax, but it starts out too loud so has not much room to go. Not only that, it gets there too soon and just stays there. It's stuck and can't get any more dynamic. Track 13 (Angel Calling) is one of my favorite songs, but not the one on this CD. The one on "18 Bangai no Kiseki" is way better sounding. That's too bad because I'd have liked this one to be just as good since this one is her solo whereas the one on "18 Bangai no Kiseki" is a duet; not that I have anything against Nakao Ryuusei.
It's a real shame because Iwao-san has wonderful singing voice.
