★★★☆ Listening to “Slaves To The Grave” feels a bit like doing homework… and I mean that in a good way, mostly. The album defies expectation at every turn. It’s got a lo-fi production aesthetic that belies the excellent musicianship and sonic craftsmanship that lurks throughout the whole album. Also, while the musical mainstay here is clearly a speedy thrash, the studious and patient ear can pick out variations in the music evocative Ministry and Gwar — two bands obviously shaped by Rigor Mortis in their overlapping histories.
