kovalmoog's video: Tangerine Dream - Live in Berlin 1981 part 3 of 4

Third part of concert. Is this a 100% actually played concert? What percentage is sequenced, played and... tape playback? Observations: - "Kiew Mission" and "Force Majeure excerpt" sounds exactly as the recordings on their original albums (except for some FM-like chords at the end of Force Majeure, maybe to link it with final theme "The Price") - I can't recognize any playing gesture that matches any musical passage, and even so, any time that Franke's 960 Moog Sequencers are shown they are perfectly synchronized with the back sequences (even at earth-point). - Those sequencer are synced even in "Kiew Mission". Tape-to-sync ? What for ? - What Johannes are doing in final "The Price" theme ? Playing and stopping ? I know these questions are not very welcome, specially by TD fans... but... are we need to be blind in front of these facts? If their 70's concerts were pure-analog-nerve improvisations, and all of them were differents (even with a few days between them)... when they stopped to play on stage? Just when the hybrid technology (analog sound - digital control) gaves to synths more stability and, hence, more reliability to play them live ? I always will ask myself these questions. Suggestions and points of view will be welcome on comments.
