Toccata and Fugue is not the only organ music out there. And "horror/vampiric" is to the eye, er I mean EAR of the beholder. T&F in D-miner never struck me as being "vampire" music, moving yes, but not in that direction for me. Gothic Rock or Gothic or short goth has a lot of "vampire" music which is something "new" because no one actually wrote "gothic" music in the old days. Such pieces as which you mention are tributes to the Church and God... holy, sacred music if you will. You might want to pursue the Requiems of the classical Artists. A requiem is in essence a funeral piece. Examples: The Requiem Mass in D minor (Mozart) http://youtube.com/watch?v=d88xIIRDI9U (You tube with orchestra playing the whole piece) I have heard it played (at least parts) on organ. If it is strictly organ music you must have, then I would suggest reviewing Sonatas and organ solos. there are many out there. Organ piece (you'll have to look it up further) http://www.mvdaily.com/articles/2002/03/cacd1032.htm Another where parts are Organ music, haunting, death related music of the old kind: Overture to La Princesse Jaune Requiem Symphony No 3 in C minor - Organ Symphony I mean there is a lot out there, depending on what you think of as "vampire" music. If you have lime-wire or similar you may want to do a search for Organ Music. A little help may be this site: http://www.orgel.com/home-e.html which links to music piece on organ. That link: http://www.orgel.com/home-e.html That should keep you busy for a while.
