""Carnival of Lost Souls" though primarily a dark cabaret-style album, also contains a heavy metal song, while the music on the "Blood of Angels" album blends industrial dance and tribal rhythms with ethereal-style vocals.Vocals and narratives are also used sparingly to help relate a story or serve as introduction to a musical piece, for example, the voice of "Jonathan Harker" and whispered female voices of "Dracula's brides" that beckon to the listener, a carnival barker with the indistinct sounds of an audience in the distance, or "Edgar Allan Poe" and a voice calling out from the grave after being prematurely buried, the gravelly voice of a "witch" casting a spell, and a variety of low Gregorian-style chanting and choirs.
