I have the one from the 80's? I won't bother with remastered versions for them. I have a lot of their stuff including virgin years but I would have to go to their site and see what I may be missing. I lost interest in them in the mid/late 80's timeframe as to me they became too happy/new-age-ish. Not as dark as their better material. Still great musicianship but with the addition of guitar to it and whatnot I just fell off the bandwagon for them. I would have LOVED to have seen them during the 80's when I got into them. I think Thief was my first exposure to them and I went nuts from there to get a bunch of their stuff going back into the 70's (some I don't like, sort of acidish stuff which at that time didn't click with me, perhaps today I will have more appreciation for it?).
But I prefer their 70's to mid/late 80's material the most (Tangram, Le Parc, Green Desert, Logos Live, Exit, etc...). I need to dig them out and dust them off as I have not listened to them in quite some time (talking yrs here lol).
