That first song sounds like USPM which should be a good thing if the songwriting wasn't shit. I mean, wtf is up with that main riff? Why did they feel a need to tack on that bit to make it not 4/4? There's no flow there and it suffers the same retardation that many bands wrote early in their career but outgrew. Show No Mercy suffered from similar but at least they were writing extremity-pushing thrash. That song is both regressive and ridiculous, and Warrior's vocals don't belong in what sounds like a slowed down Iron Maiden song. Shitty I don't give a shit about the change of style with regards to any band, but it was at best a respectable attempt at the impossible, at worst incredibly uninspired. If any demo band from 1988 tried the same... well, they'd have the same fanbase of about three people who like shit probably for the sake of it.
Juices Like Wine is decent though. But just decent. "Fucking rocks" is still massively overstating its value. Considering that you hate Iron Maiden for Bruce Dickinson's vocals, I'll assume that you don't listen to traditional metal and therefore Celtic Frost's craptastic excursion into it excites you like a guy might cum when listening to Atheist's Samba Briza or something similar.
