Testament took sizeable creative steps on their second album but lost none of the power that had made their début so damn good. It's a prime example of the kind of heavy, melodic Thrash that was doing the rounds back then. But there was more mediocre Thrash bands in the late 80s than Disney had stereotypes, and while the output from many of them sounded like little more than surplus variations on a theme, Testament had Chuck Billy and that made all the difference. So what if it had an Aerosmith cover? They somehow made it work in their favour.
