Belzebubs, the cartoon band created by JP Ahonen, will release their new record Pantheon of the Nightside Gods on April 26. Much like Dethklok, the band might be a cartoon, but the music is actually really good. It reminds me a little bit of old Dimmu Borgir, though with lower vocals.
Pantheon of the Nightside Gods was mixed and mastered by the legendary Dan Swanö (Dark Funeral, Dissection, etc.).
