Slayer's Reign in Blood is like a handful of other albums I treasure. Nevermind, Vulgar Display of Power, Number of the Beast, Forbidden Evil, 40oz to Freedom, Zeppelin II, Angel Dust, and probably a dozen others. My feeling is that there are a few select albums that really stand out as being done perfectly, Reign in Blood is #1 in that list. At no point in Reign in Blood can a listener logically say hey it would have been better done if they had done this note like this, Reign in Blood is PERFECT. Angel of Death, take it as you might as a venomous song about german warfare, encompasses the most ingenious guitar and drumwork known to heavy metal. Its not about metal, its about perfection. Slayers Reign in Blood is perfect, as are all the albums aformentioned. South of Heaven and Seasons in the Abyss come awefully close to achieving that same perfection. Reign in Blood certainly sparks an entire generation of metal in 1986 and as equally sparks 5 million jerkos that shouldnt have picked up a guitar in the first place.
