Update: Found all four.
Bump. Found a copy of "See You All In Hell", still interested in the other three (especially "We Hate Them" and "Voices.."). To the guy who PM'd me about these: thanks, greatly appreciate the effort! I sent a follow-up message a while ago, haven't heard back but I'll be in touch through e-mail a week or so from now if you somehow lack the time to check the board since I understand we've all got tons of other shit to do.
