Slaughter play a style of metal undeniably in the death/thrash vein. However, though that may be a suitable classification for nowadays, when I hear this record I can hear that these guys were playing the death metal of their day. It is a primordial brand of death metal very much informed by hardcore punk and thrash but the aesthetic is the same as all death metal. These guys wanted to make BRUTAL music and never have I heard a recording from this time to have succeeded so well in capturing this vintage sense of brutality.
If you're a fan of Death Strike, Hellhammer (anyone?), "Morbid Tales", early Death, "Seven Churches", Sacrifice ("Torment in Fire") or just primitive fucking madness, get this NOW!
