Nightmare truly cannot be compared to any other band in the Japanese music scene today. Their diverse sound includes everything from heavy beats and operatic vocals to beautiful melodies and catchy lyrics, creating a type of music that sets them apart from the rest.
Although they've abandoned their over-the-top costumes for a milder look, Nightmare is still classified as a visual band due to the extravagant make-up and wild contacts usually sported by guitarist, Hitsugi. Not only are the five members of Nightmare dynamic musicians and performers, they are also humorous individuals who use all aspects of their personalities to show off what they can do.
