"Black Butterfly" by Electric Wizard is a song that depicts a dark and haunting scene. The lyrics describe a terror that is personified as a beautiful butterfly, flying through the vastness of space to reach a forgotten place. The song then shifts its focus to a gathering of druids at a circle of stones, where they engage in worship of the ancient ones. As the sun sets, these druids begin their rituals of evil, with sinister intentions. The presence of evil monks is mentioned, who need to remain oblivious to the black colossus, suggesting a looming danger or entity that must be avoided. The mention of crystal shards falling and filling circles in their minds portrays a sense of corruption and distortion. The lyrics take a darker turn as they introduce thirteen maidens who are destined for sacrifice. These maidens, in their helpless and vulnerable state, will slowly perish in a disturbing manner. The imagery of blood mingling with crystal drips ice creates a chilling atmosphere. The final line, "Open caverns of eternal midnight," further emphasizes the song's eerie and menacing tone, suggesting a perpetually dark and ominous realm. Overall, "Black Butterfly" by Electric Wizard delves into themes of darkness, evil rituals, sacrifice, and the eternal night, creating a macabre narrative that seems to explore the horrors of a sinister and forgotten realm.
