Demented Christmas music is one of my specialties...

May I recommend the following albums, which I have on CD, and will probably turn up in dumper bins across the nation...

Christmas Cocktails -- look for the "Ultra Lounge" at the top. Record label: Capitol.
I am Santa Claus, and Twisted Christmas -- two cd's by the very strange Bob Rivers, label: Critique
The Nightmare Before Christmas -- on CD, and just released in a special edition DVD and video with bonus footage!
Christmas in the Stars, The STAR WARS Christmas Album, from Rhino records.
Dr. Demento presents the Greatest Christmas Novelty CD, also from Rhino.
A Toolbox Christmas -- by Woody Phillips, Gourd Music
Ho Ho Ho -- by RuPaul. (Need I say more?) Rhino.

And if you want pretty strange but sometimes also pretty pretty, look for Excelsis or Excelsis 2 from Projekt records. Christmas music by Goth bands...

You asked for it. {grin}
