it's hard to explain, because Lunaris is unique and very special band with own style. i never heard band who united two diffrent style like black metal and progressive rock, but there's is LUNARIS. once i spined their mp3 with my wife (she is vocalist) and my friend (he is keysmaster in black metal band) and we attempted classify Lunaris... in our opinions Lunaris is something between black metal aggression and Dream Theatre and Spiral Architect + something else. once there's is fast black with furious screams, once Lunaris is progressive riffs, beauty keys passage and clean vocals. but... you'll must listen Lunaris oneself
