Scream bloody gore, also the demo on the cd is very good. SBG is more raw, primitive and angrier than later albums, also it's the first album I bought from Death.
I used to have Human once upon a time and never really got into it. I picked up Symbolic and The Sound of Perseverance awhile back and enjoy both. I'd give the nod to Symbolic right now. Still need to listen to the early stuff. The first album is kind of awesome as I've come to prefer the Old Skool DM sound over the brutal stuff I enjoyed as a teenager.
