You can achieve this cassette here but the best news is that the boys at Pesanta Urfolk have already forged this beast in wax, so what are you waiting to get your claws on this outstanding piece of pure evil? Support Hell and also the hard working guys at Eternal Warfare and Pesanta Urfolk, all great guys to deal with. Don't need to say that this is Highly Recommended..
forged in Hell
