From my personal dealings with Blake, I have no reason to believe the things said about him there are true. I know many people who have worked with him musically and through business, and no one has anything bad to say about him. He's a very friendly and open guy, and a lot of people want to work for him/be on his label. On the other hand, you never really hear anything positive about Moribund, do you? Especially following their issues with Malefic, and now this.
I fear the drug stuff about Wrest might be the case though. For someone with such a prolific recording history to suddenly stop for two years or so like that is very odd, record disputes or not. Also, from what I understand, there was never a true Lurker of Chalice thing in the works. It was most likely Leviathan material to be released under that name. The sample track out there does sound more like LoC than any other Leviathan material, though. If the resulting music from all of this is somewhere in between the bands, I won't mind.
Wrest was really on to something good with The Blind Wound. I hope it continues.
