Both of these tracks will appear on the new album.  Although the verse vocals on Gilgamesh are guide vocals by Gobz and will be replaced by another singer/singers.

Messiah is a live session version and the drums in particular are not meant to be kept, in fact the drum patterns on the long bridge parts are not correct.  And yes this is just a thrash/Death metal type of tune and probably more suited to our Corporation of Corpse Stealers project, however it was written a long time ago with inclusion on the WHores album in mind and we used to like to stick 1 thrash track on albums ( see Stigmata on the Metropolis album )
