UMUR
"Nocturnal Hell" is a single/EP release by Canadian thrash metal act Slaughter. The single/EP was released through Fringe Product in 1986. All three tracks from the single/EP were recorded during the samme February 1986 sessions which spawned the material which ended up being Slaughter´s 1987 debut full-length studio album "Strappado". In fact all material from this single/EP appear on "Strappado" in exactly the same versions.
So in that respect "Nocturnal Hell" is a bit redundant these days, but back then the single/EP of course functioned as a teaser for the forthcoming full-length release and it should be evaluated on its own merits. If you´re familar with the preceding demo releases by Slaughter the raw, aggressive, and hardcore tinged thrash metal style found on "Nocturnal Hell" isn´t a surprise. It´s slightly more interesting material, heavier, and darker, but other than that this sounds a lot like Slaugther also did on the "Surrender or Die" demo from April 1985 (maybe with a few less heavy/speed metal influences). A 3 star (60%) rating is warranted.
