NUNSLAUGHTER's best work is considered by many to be their EPs, and Devils Congeries - Vol. 4 displays the band's trademark Devil Metal in all its diabolical 'n' dirty glory, collecting EPs and splits from 2006-2010: splits with Destructor, Unholy Grave, Syphilitic Vaginas, Zombie Ritual, Sloth, Goat Sodomy, Mutilated Messiah, Fetus Eaters, Radiolokator, and Evil Wrath as well as the Fuck That Cunt and Fathers of Fright EPs and the aforementioned Damned in Japan 7? boxset and Novel Nasty Nugget compilation LP. Adding to that rare inclusion of the Damned in Japan audio is a reissue of the Damned in Japan DVD, previously released by HELLS HEADBANGERS in 2008 but long out of print, which documents an Osaka show from 2005 where NUNSLAUGHTER were welcomed as reigning kings.
