WTF is "Waking the Cadaver"? Sounds necrophiliac.
The best grind is like the best punk: cynical, but not leftist/revolutionary. Over the top, but not comical. Humorous, but serious about their music.
Idiots try to distill the music into one of those extremes and the result is moronic shit that gives the genre a bad name, which is why death metal fans tend to shun grindcore as a tardherd -- unjustly so, in 2% of its cases.
