Sweet child in time! The live version is more full voiced.

Planty at the end of "Whole lotta love" (or most of the Zep cannon, thinking about it) is good too.

Right before the album version of Another Brick in the Wall pt. 2.
Intro to TV Eye by the Stooges has a good one, I think, or possibly Loose. Or both.

Must have done a good scream somewhere.
Land of 1000 Dances perhaps?

I minute 18 seconds. Short but pretty blood-curdling

...has some bloodcurdling screaming on it. You might have trouble separating it from the music.

You can find the song on youtube. I won't link to it directly as the image for the link is of a naked woman, streaked with blood, standing in front of a crucifix. This is why you preview posts.

Give me a week and I can probably provide you with the tortured screams of either Wet Wet Wet frontman Marti Pellow or Ronan Keating.

by Rhoda & Special AKA has the most chilling scream in all recorded music (in context, at least)

But BROTHER BROWN's must be the most recognisable by far! And there are hundreds of shrieks and whoops to choose from.

Having clicked 'reply' twice...

Jan Tiegen's original Nul Points Eurovision entry for Norway: Mil etter Mil

The scream's at 02.40...

Failing that, the way Prince screams 'Ain't no particular sign I'm more compatible with' near the end of Kiss...

Oh, and of course James Browns 'WAAOOH!' from 'I Feel Good'. Or 'Get Up Offa That Thing'.

And then there's 'Psycho' by The Sonics.

Most tracks really
Tame off of Doolittle for starters...

Here's a few that come to mind. I hope quick yelps and yeahs are allowed. Quality not quantity.
Psycho - The Sonics (0m2s) (Woah!! at the start & towards end)
Revolution - Beatles (0m5s)
Personality Crisis - New York Dolls (0m6s)
As Jon suggested, you've got to include an Iggy one.
The Golden Age of Rock 'n' Roll - Mott The Hoople 2m30s
Bellbottoms - Jon Spencer Blues Explosion (2m20s) (Yaayah!!)
Mutiny In Heaven - The Birthday Party (0m0s + background screams throughout)
Stagger Lee - Nick Cave (4m9s) (I think it's Blixa Bargeld)
20th Century Boy - T-Rex (the background scream at 0m3s)

And I know it's not quite what you're looking for, but Pixies-era Black Francis is my favourite screamer: see "In Heaven", "Wild Honey Pie" and the maniacal laughter on "Debaser".

The last Kings Of Leon single had a bit of screaming on it, if I remember rightly.

At the beginning of Transvision Vamp's "Baby I Don't Care"

It's where I'd start...

Frankie Teardrop by Suicide. Quite a few bloodcurdling screams throughout - not really a pleasant listening experience though.

Your Iggy solo scream should be the one at the start of TV Eye (original Stooges version) and your Ian Gillan the long, very long solo scream at the end of Deep Purple's Strange Kind of Woman (live version, Made in Japan). You might also want to consider Bowie's 'aaaahhhhh' just before 'wham bang thank you ma'am' - certain I don't need to say the track and album here.

The Girl Can't Dance by Bunker Hill.
Johnny Burnette & The Rock n Roll Trio's All By Myself has some fine screaming in it as well.

At the beginning of When The Music's Over.

Also, some 1969-1970 Lennon. Cold Turkey's pretty good.

C major 7 from Valhalla Avenue by the Fatima Mansions opens with a real blood curdler

Father, I want to kill you......
Mother, I want to AAAAAAAAAAARGH
(Same song)

Does "Werewolves of London- owoooooooo" count?

It it counts...

Brian Connolly at the start of "Hell Raiser"

Diamanda Galas.
Carina Round.

Hello, can I suggest a couple that can be found on the Afghan Whigs' Black Love albumrecordcd...midway through Bulletproof and at the end of Faded...(although its more of a yeah yeah yeah in this one)

Mighty roars both!

A subset genre of scream?
Fire/Arthur Brown
Race with the Devil/The Gun

Bruce Dickinson - Aces High and Hallowed Be Thy Name come straight to mind - he hits a lowish note and starts to rise up and up into a scream. But to be fair he does shout a lot !!

Ian Gillan - Child in Time (with Deep Purple) I think he gives Plant a run for his money on this. Some of his solo stuff had some pretty good screaming in as well. Stuff like Nightmare, Mutually Assured Destruction, Born to Kill, Hadely Bop Bop, No Laughing in Heaven etc.

...Bobby Parker really lets rip on 'Watch Your Step'. It's right up there with Wilson P, imho.

The intro to Man Out Of Time.

I'd go for his version of Engine No 9 for some excellent scream action.

not to include Mr Cobain here - can I notimate the chorus of Scentless Apprentice or perhaps the 'shiver' moment in the cover of Where Did You Sleep Last Night?

followed by impressions of an unanaesthetised cat having a caesarian....

I suppose Timbaland's current chart hit 'Scream' doesn't count? Dare Imention his name in The Word?

As heard every time I see another picture of Cherie Blair in the papers.

With A Little Help From My Friends. Preferably the Woodstock version. Now that's what I call screaming. 4.57 in to the track, he really gets going.

Otherwise, anything by Extreme Noise Terror or Whitehouse. Come to think of it, Media Friend by Rudimentary Peni is one continuous scream. Yesterday Has Gone by Cupid's Inspiration has its moments. Tin Soldier by The Small Faces. Let us not forget the tremendous 26 minute Cambridge '69 by John and Yoko.

Actually, that's my favourite. John & Yoko.

Crime of the Century. School. 1'44". It's all you really need

How about Roy Harper's 'True Story' from the Unknown Soldier album, where he acts out the screams Edward II made when murdered by having a red hot poker shoved up his arse!

You lot have missed rocks most essential scream, namely that in 'Won't Get Fooled Again' issued forth by one Mr Daltrey.
