Well, haven't had time to listen to it or watch it all. Once you heard APSOG once, I for one don't have the urge to watch another version of it in its entirety, but I'll let you guys know.
The specifics are:
Disc 1: The original album version.
Disc 2: Live in europe (don't know if this is the same version that was on 'Still Life', but if it is I'll feel pretty much buttfucked, but anyway. it also has 'In trance' on it, I guess a cover version.
Disc 3: Probably the most interesting, because its various stages of demo-ing.
Disc 4: The DVD with two filmed concerts, the first is the 'Live in Europe' which was released earlier on vhs etc and one filmed live at the Whiskey.
