slayer :not really thrash (darker & more macabre)but not quite death metal either. whatever the hell you call it, the sound of slayer is never sweet ."south of heaven" is'nt the heaviest slayer album ,nor is it the fastest or most evil.what it is (in my opinion)is the most entertainig slayer album .i hav'nt heard any of their recordings after "seasons" but my slayer collection is an unbroken chain from "show no mercy" to "seasons".
