Finnish band number something! These guys are playing mostly on other bands so this is more likely only side project for them sadly. Drummer is from Ghoul Patrol, keyboardist from Shear as well as the other guitarist and so on.
The Nibiruan’s style is progressive/melodic death metal I’d say. Maybe a bit similar to Meshuggah. They had a little lineup chances a year back, in this song you can hear their old vocalist who is now with Kiuas.
