Late 80's style death metal tribute(/parody?) band formed by:
Anders Nystrom (AKA Blakkhiem) of Katatonia and Diabloical Masquerade,
Jonas Renske of Katatonia,
Dan Swano of... well... just about EVERYTHING... Edge of Sanity, Nightingale, Unicorn, Odyssey, producer of many records, etc.
and of course, Mikael Akerfeldt.
They've released a 3-track EP called "Breeding Death" which kicks ass, and Swano finally backed down from his "NO METAL!" stance, so a full-length is apparently forthcoming. My understanding is that Nystrom writes the majority of the material.
