Exactly. I don't get the Corpsegrinder hate. He's actually intelligible without sacrificing that brutality of good death metal vocals. And he has a decent range.
Chris Barnes' vocals actually deteriorated when he started SFU. The vocals he's done since with Severe Torture are better, but I'm afraid he's just lost it altogether.
I can actually emulate the 80's metal style clean vocals (though not quite good enough to seriously pursue a career as a vocalist), and basically it is regular clean singing. Using falsetto and upper-midrange tones, blended with a little bit of nasally "twang" and scratchy "vibration" of the vocal chords reproduces the tone of the "hair bands" fairly well. It doesn't sound right unless you really belt it out and wail. I used to play bass and sing backing vocals in a cover band in which we played a lot of hair/80's metal songs and the vocalist taught me his technique. It's pretty simple, but to sound good depends entirely on one's level of talent.
Why are there no real Metal shows on the web or anywhere for that matter?
