I'm not sure how to sell you this with words, but you're not buying anything so just download while you're reading. First Blood are consistently awesome across both these demos. Everything you want from awesome Thrash is here and awesome - Riffs! Solos! Six minutes songs! Engrish! Well, not quite...the chorus of None So Blind from Silent Summoner used to throw me when I was listening to it off A Taste of Armageddon. Slightly awkward lyrics and delivery, but it grows on you and None So Blind is probably the strongest song here. Brew and I were talking about the new vocalist on that latter demo - tunelessness doesn't matter for a Thrash singer if he can belt a song and make it darker and uglier than it would've been. That means we both like him. Y'all buy Slayer albums en masse anyway so you know what I'm talking about.
There are also lots of extra songs about poo. Enjoy.
