This music is part of the Blade Runner soundtrack. It matched the mood of the movie perfectly. The treated piano sounding a little bit cold and off tone is layered on top of a warm melody, which together suggests the sadness of the human clone and its slight imperfection.  The blips and woosh give it the sci-fi hi-tech gloss.
If it does not load properly, watch it on Youtube.

The entire length of the piece was not used in the movie and it was not included in the movie soundtrack. The music was released first in Vangelis’s studio album “See You Later” (1980) which I have not listend to from beginning to end even to this day.  The piece was released again in a collection of Vangelis movie music in “Themes” (1989).  I loved Blade Runner and remember searching for this track for a long time after the movie came out.

I wonder when they are going to make a sequel or prequel. Hurry up people.
