depends on what you call pissed off but if its metal then Zach de LaRocha of rage against the machine
well I don't listen to much like this, but I'd have to say Johnathn Davis in earlier korn... side note, I heard there new cd is good.
god dammit. I voted Corey Taylor but seemed to have overlooked Jamie Jasta. Eventhough Corey is in my top 5 metal vocalists i still choose Jamie as the angriest voice.
That "I fucking hate you" from the song A Call for Blood by hatebreed has got to be some of the most pissed off vox I have ever heard. I have just recently got into them, their new album is pretty good too with plenty of pissed off vocals.
Im with Garcia kinda...Zach doesnt sound (I guess...I dunno) very pissed off vocally...but his lyrics tell you he's pissed off lol...anyway... I like Henry Rollins durin his Black Flag days...but he still sounds "pissed off" in Rollins Band...so yah
Frank Mullen of Suffocation - listen to the Human Waste version of 'Mass Obliteration.' Amazing. (Must be Human Waste version for full effect) Lord Worm of Cryptopsy - try 'Slit Your Guts.' (He's back in Cryptopsy! Go to the site www.cryptopsy.net, there's a creepy message from him) Joh Chang of Discordance Axis - Almost any song will do. Those would be my top three, but out of the list you gave, I'd go for Phil, definately.
i voted corey taylor of slipknot ,acully i havent HEARD all of those vocalists but me who used to be a HUGE slipknot fan am really fond of the way he does his music
