Props to Precision Sound who have just released their 'Demonic Voices from Hell' sample CD, containing "unprocessed performances from professional singers and voice artists in the darker heavy metal genres" for $50. Assuming you've got headphones on and are not of a sensitive nature, I'd recommend you listen to this ace MP3 sample, which appears to say: "Torturing! Timbuktu! Slaughtering! Porno!" (Thanks, Sonic State)
