Straight from the official Union Carbide Productions website comes this news about the upcoming box set:
Each of the remastered CD's will most probably contain 4 bonus tracks. It hasn't been decided which songs just yet though. Ebbot also wants to put in a bonus CD with live material. Another cool thing is that there'll be a section in the liner notes where Ebbot talks about how every song came about. Next week there's gonna be a meeting where they'll decide upon what to put in the box and what to leave out.
