Most people I know haven't heard [link|http://www.the-sisters-of-mercy.com/|The Sisters Of Mercy]. I suspect they don't get any airplay due to song length(two of my favs, Dominion and This Corrosion, come in at 7:01 and 10:55 minutes respectively).
Orion, you can find some MP3 samples of their songs on their site, including the suggested When You Don't See Me.
