[Machine Translation] Amiliyah, a heavy and melodious band consisting of a princess imprisoned in a tower and five monsters, will release their first two concept albums in two and a half years. The first one is "HIDDEN DOOR" with the theme of "Darkness". What's behind the "hidden door"? The album includes new songs after new members joined, songs that were well received at live performances, bold rearrangements of songs from the first album, and many other gothic and industrial works that are not limited to easy interpretations of "darkness".
