Witches are generally very nice people.
Fortunately there is also a metal genre witch is rather pleasant as well, so I'll start with the following.  Might be going out on a limb a bit here, and the minutiae of the category may be questioned, but the music is good.  As ever thoughts and contributions welcome.  Plenty of Witchy caves around too...
