I've never understood why this album didn’t achieve the same attentions as the early Metallica and Megadeth releases did critically. It’s certainly got the power and the technical proficiency to keep it in the best of 80’s thrash lists. The sound is a mix of early Metallica and Exodus, what is now the classic Bay Area thrash sound. The production could be better but the enthusiasm and the urgency with which its delivered is faultless. Testament matured and changed on subsequent albums but they never bettered this for pure in-your-face entertainment.
