Polish Whorehouse blend thrash sounds of the past with newer trends. More specifically, I think you could say they bring together Kreator and Machine Head in a fashion that to some extend works fine.
The comparison with Machine Head and Kreator is very much sparked by the voice of guitarist/vocalist Seba who in some odd way sounds like a amalgamation of Mille and Rob Flynn. It has a lot of thrash in it, naturally, but it lacks versatility too, sadly.
Versatility is an important point here. The ten tracks on ‘Execution of Humanity’ are very alike, and therefore have a tendency to become background noise. You could argue that this is just a homogenous album and if the quality is high enough, then so what? Well, yes, but the thing is that there are fillers on this album, where as others are superb little masterpieces of thrash metal.
If you go through the trouble of finding the album, the extremes of the album can be illustrated by the excellent slightly Sacred Reich inspired track Slow Burn and then at the other end of the spectrum the entirely superfluous middle-of-the-road thrash tune Drink Till Xodas.
A solid piece of work, but you can find better out there.
