One has to be in the proper mood, too.

My favorite is Halber Mensch, perhaps because it was the first I heard (on a college radio station - I miss those days). Tabula Rasa is a nice album for me because it has a nice mix of the ambient (Blume) and the noisy (Headcleaner).

Swans are another of those bands that I love, but find very few people in my circle who agree.
