Energetic Disassembly 1985

"In many ways, the mother of technical extreme metal, "Energetic Disassembly" and WatchTower constitute the precursor of acts like Death, Cynic, Pestilence and Atheist. And if you like technical and progressive metal, then this collection of complex, mindboggling thrash metal tunes should be right up your alley. While the guitar sound is crap, the stereo effects on the drums are sick (in a good way), and the bass is nicely prominent like in Iron Maiden, Cynic and Atheist."
