Query: Underrated

I have to say something about this particular band/album: it was released down here in Brazil in 1990 or so, and as far as I know I was the only one in my friends metal network who got it. Actually, I might be one of the few who bought it in the whole country. I doubt it sold over 50 copies overall.Which is just unfair, since it is a fine power/thrash metal album, with skilled musicians and a fine singer. The drummer is amazing and the twin guitar work is above average. Although the music is awesome, the package didn't help at all because any 8 year old kid would've come up with a better sleeve.The timing wasn't right either, since thrash metal was starting to descent and alternative heavy rock (or any other name they call it) was getting popular all over the world. Then Seattle came and smashed it completely.Nevertheless, if you're a metal fan who enjoys fast riffs and drumming, screaming vocals and the ocasional fair melody... go for it. It's at least worth checking.
