Osaka Trade performed Flying Lotus composition. Probably, and correctly, that such trailer melody rather short – only 2:41. But it is full of pleasant high male voice (most likely, it is the voice of the man-eunuch, as in the Desert Rose song by Sting). Oriental motives, with which this song permeated completely, pleasant and somehow evoke the mood of Act II in the Diablo II computer game, where the main character runs in Oriental lands.
