"Sins meats* Naxxramas" and "Naxxramas continued "series now form a complete Naxxramas video serie.
Most of it was done before Burning Crusade with guild Sins, but the remaining bosses (Thaddius (Phase2), Gothik, 4 Horsemen, Loatheb, Sapphiron & Kel'Thuzad) were film in high-end-PvE-players pick up raids (some had participed to the Kel'Thuzad first kill in France) on EU-Illidan in April-May 2007 and the very last videos last videos were added this month : "Dead Knights & Mushrooms" and "Naxxramas Erotic Mode (outtake)" version 2.
All the soundtracks were played by Kerion ( http://www.kerion.net/ ) French symphonic metal band who's singer was the girlfriend of a Sins guildmate. (You'll see some band photos in the ending/thanks of "Dead Knights and Mushrooms".)
* Note : I know the difference between "meat" and "meet". "Meats" is a play of words based on "meat" and "meets" to put the accent on the slaughter !
