Synth soundtrack of the solid variety, beautiful Ominous

Film music often has the disadvantage that it says little without the film. "Thief" by Tangerine Dream is one of the exceptions. I knew the music before the film. She had, of course, fit into a thriller and is less epic and therefore meditative than the others in that period of TD released albums, also the pieces are more compact and much shorter.
Although this the 1981 soundtrack not quite to my personal Tangerine Dream-favorites "Force Majeure" (chronically underestimated!) And "Rubycon" will come, may especially be "Diamond Diary" still easily make a movie my mind's eye. Grandiose! And "Dr. Destructo" with its reality-distorting guitar sounds seemed in the early 80's sound as structurally very modern. For "Igneous", the last piece, have Edgar Froese and Co. a passage from the worth listening to "Thru Metamorphic rocks" recycled (from the mentioned album "Force Majeure") and still draufgepackt a Sound Layer, of a hectic synth sequences rotary offset into Unheischwangere. The result placed in record time in trance like states.
What I can not understand until you see today: Why is the music of the final scene of the film not on the CDF? They only appeared as a bonus track on a part of vinyl editions, called "Confrontation" and reminiscent of David Gilmour's guitar solo on "Comfortably Numb". How can you leave something Successful?
