[Stardrowned]

The Red Chord are my favorite grind band, you can download a live version of "dreaming in dog years", which is there best song, off their website. It's theredchord.com if you couldn't guess. also some other grindcore bands would be:
Cattle Decapitation
Daughters
Employer, Employee
Soilent Green
Extreame Noise Terror

and i know Roboticempire.com has a circle of dead children mp3 and some pig destroyer videos plus other grind to download.
