Can’t say that I know too much about these guys other than that Gordon Tittsworth of Images Of Eden performs the vocals. The Images Of Eden album was a mixture of progressive metal and traditional metal, which was almost too heavy for my tastes. Spiritus Mundi tip the balance and this is definitely too heavy for me. I’m sure there are more modern reference points but this reminded me of a mixture of early Megadeth and Metallica, complete with biscuit tin drum sound.
From the start of the album these guys play really heavy music that tells me they are pissed at the world, or at least the American government, although to be honest I wasn’t interested enough to listen too much to the lyrics. Most the tracks are a mixture of trash metal with maybe a bit of death metal thrown in a well. I found all the tracks to pretty much sound the same, with little to distinguish individual ones. About the only notable moments were that "Wake Up and Die" sounded a little like early Ozzy solo stuff and that the final track lasted for 14 mins.
So essentially a type mismatch with my personal musical tastes. There may be something in it for those who like really heavy stuff, but I think even then are better examples of the genre out there.
