"Enter the Grave" is faster than the studio version, but its not musicaly not written right yet & it was song in is "matured" voice, like on "infected Nation". "Death Sentence" was eh, but "Russian Roulette" is a must find !

Enter The Grave - A bit faster than the original, but as a demo, well produced. Drums in the whole demo sound raw and it works so well.
Death Sentence - Not really the fan favourite, but the solos are pretty cool and I can listen to the bass intro ALL day. Trust me.
We Who Are About To Die - A bit disappointing around the time where Matt screams "WE WHO ARE ABOUT DIE! SALUTE YOU!" but as a demo, it's great.
Russian Roulette - One of the more unique tracks. All I can really say is that it picks up after the intro.
Thrasher - The only thing about this that I can say about this track (besides it being AWESOME) is the Schwarzenegger voice near the end of the it. Funny as hell!
