As we get closer to Halloween my mind turns more and more towards the murder ballad, not necessarily a blues form, but I think closely related. There are quite a few blues rock renditions of some of the classic Murder Ballads. Let's see what I can dig up between now and Halloween.
First up are a couple of tunes, one "Graveyard Train" by Creedence Clearwater Revival and the second one, by a group called The Graveyard Train doing their song "Ballad for Beezelbub". How cool is that?
