While surfing last night, I saw this movie available on Amazon. I was attracted due to Patrick McGoohan and Lee Van Cleef in it. The movie itself was pretty dire, (produced around 1979) but the score, while minimal sounding and sparce in quantity seemed nice, and I watched it all the way through to see if the composer was mentioned.
At the end I saw Brian Eno's name mentioned, but that was all. A google search today showed this onIMDb:
Events In Dense Fog from album "Music for Films" Music by Brian Eno Courtesy of EG Records
Will be putting this on my Xmas list.
