So anyway, it's a great greek black metal band with a Gothic type feel to their music. Early Demos were influenced more by Grindcore, before they became a fully blown black metal band. Like I said, They've been around for more years then their Norwegian Black metal musicians so they are highly influential. Lyrics usually talk about Greek Mythology and love which is definitely something new in black metal.
100x better than Dimmu or Cradle.
