2018 release. After more than six years since The Book Of Kings, Mournful Congregation, Australia's stone pillar of funereal dirge, presents their regal fourth full-length, The Incubus Of Karma. Since that time the band has made several trips to the U.S. and Europe, released the mini-album Concrescence Of The Sophia, and increased their reputation as the pinnacle of extreme / funeral doom and as one of the most influential bands in the genre.
