Razorback was a real surprise for me, because like you said, if i had watched it in my Splattepunk and Gorehound days it would have been an instant favourite in the same top league as movies like Phantasm, Evil Dead, M.A.R.K. 13 or Hardware, Basket Case, from a creative visual approach, style over story, but i also recognized a weakness which i would have then seen as a strenght, and that were those two evil dudes and their overacting and their role in that film. They were real scary, more so than the monster, could have been ok, but i felt it was kind of unnecessary and wanted. But anyway, i was in total very pleased with that experience, it felt nostalgic...
The soundtrack wasn't a gift from my friend but from Dieter, i think he had a meeting with a later manager or someone involved with TD and then he got that copy for me, he didn't own one. He has many first pressings vinyls though. I haven't listened to it yet and i hadn't read the comments in discog and this whole situation with the soundtrack is kind of weird. So as i understand it now, the only TD licensed OST of The Keep is that release, but it features many songs which weren't in the movie and also it lacks many songs/themes that were in the movie.
The only other release is also from TDI, on the remastered 2020 album box-set Pilots of Purple Twilight, which only has 13 songs, the older TDI release has 16...
The Orange Records bootleg release is available for 40€, it has 4 more songs than the early release, seemingly taken from other TD releases.
I don't get this story with the bootleg taken from a LD. It could be a version of an isolated score featured on that disc, i love that feature!, but then you don't have the songs of a soundtrack, only parts of it. Or it was an edition with an extra soundtrack.
