If you like Slayer, do not even think about missing this CD. Same goes for any thrash fan. This has some of Slayer's best songs - Hell Awaits, Kill Again, At Dawn they Sleep, Necrophiliac and some of their most inventive riffs period. Reign in blood was more of a "lets' be the heaviest band in the world" record, while this has Slayer trying to get creative, and actually use a few different sounds (Crypts of eternity - the back and forth singing of Tom, etc etc) There's no filler on the album, unlike on Reign, because Reign had a more monotnous sound, too "kerry king" heavy. This more "heavy" crunch approach on Reign has led them to lose the "evil" charm displayed perfectly on Hell Awaits. The lyrics aren't that ridiculously dumb on this CD either...a few of the lines on Hell Awaits actually had me thinking of how Kerry could possibly come up with that (Kerry!). The amount of riffs per song is quite impressive compared to RIB, and they're all such great Slayer, and thrash-defining riffs. The riffs were not as downtuned, so you could hear the bass, they were not burrowed or lifted from previous songs (in RIB you can hear the Hell Awaits riffs) , they were not as simple, and also were evil and very memorable. 1985 was the time when Slayer was still young, when their material was at the most creative state for their time. This is a masterpiece, and RIB was also great, but this is better imo. If they re-produced it , everyone would probably notice what I'm saying - but don't let the production fool you one bit! (it's not bad anyway)
