Sodomy
I agree with Gaz, Anal Rampage would be a killer title.
I also think the dominant riff was in Lost in Purgatory too, which is even more revealing to the fact that if I submit my song 'Slaves of Egypt' to NG, people will think I ripped off this riff.
Awesome fuckining stuff, now start your anal rampage with the nearest dog you see, which was my former career (haha I remember writing that when you had about 40 songs on NG.
