Another song that really sticks to my "inner jukebox" is "Equal Ways" on their eponymous first album in 1985 (was it their first?). It has a "foggy" sound and a mechanical beat, which provided a good musical backdrop in my mind while visiting places in Germany and Switzerland in the winter a while ago. I'd play that song in my head while observing timely trams and frosty fog in cities like Zurich.

Also, when I was visiting that cathedral in Strasbourg, that spooky intro to "Stranger" with the deep voice chanting a latin prayer was running through my head loud and clear while looking up the almost endlessly high ceilings of the chapel.

"Atmospheric Rock" is what I remember the Clan of Xymox as being classified as by 4AD.

I actually welcomed Hidden faces... as at least a return from
the Metamoprhosis style. With Metamorphosis, I figured it was
the end of the band. Songs like Wailing Wall on Hidden Faces
for some reason reminded me of Dead Can Dance... which is
always a good thing in my book.
