Angriest Lyric/Vocal

My all time favorite after Colbane. Vedder doing Lukin(pearl Jam).
"I'm gonna Lukin"skreeeetch. No code never gets any love and it sounds great< not often angry, am I on the wrong thread???? na!

Dixie Whiskey by EYEHATEGOD from "Dopesick"
or
Det Som Engang Var by Burzum on "Hvist Lyset Tar Oss"

Lennon-Gimme Some Truth
Lennon-How do you Sleep?

Public Enemy -- Fear of a Black Planet, "Burn Hollywood Burn"

I see numerous citations to heavy metal (which always impressed me a loud and obnoxious, but not necessarily *angry*), folk/protest rock (which strikes me as earnest and frustrated, but not *angry*), some post-punk/grunge (slightly angry, but only because they are sooo sensitive)...

The Sex Pistols is a start, but for pure, unbridled, white hot anger... The whole US hardcore scene--Minor Threat, SS Decontrol, the Germs, Millions of Dead Cops, Black Flag... Those were some pissed off people.
