There are 2 bands with the same name.
The epic-Black-Death-Metal-sounding band is from Germany.
The others are playing swedish Death Metal from, uhm… Sweden. I guess you guys are able to hear the difference.
If you like the epic version from Upper Franconia, Germany click here and use the „like it“-button: http://www.facebook.com/imperiousmetal
If you enjoy the swedish guys click here and ask for friendship: http://www.myspace.com/imperious666
Both would be best.
