Psalms of the Moribund was released through Grindethic Records in March 2007 . Like its predecessor , the album received mixed reviews , with Erik Thomas of webzine Teeth of the Divine saying , " With ultra deep , almost grindcore styled burps layered over complex yet savage riffs , Defeated Sanity , unlike some of their US peers , do manage to throw in some nice grooves and lurches amid the blasting carnage , hence the Suffocation and Devourment comparisons , but otherwise , Psalms of the Moribund is a pretty breakneck assault of squealing , pinch harmonics and ravenous blast beats . " Chronicles of Chaos reviewer Kostas <unk> criticized the vocal style of Jens Staschel , stating , " The constant low guttural growling is completely unintelligible , used more like a ( very blunt ) instrument rather than a means to convey lyrics .
