Oh, I like the Blood Brothers screams a lot, too.

oh god i love saetia's aHAHagAShhAAA extremely high pitched jumbl

pg.99 definetly followed by city of caterpillar

i dunno, a lot of screamo vocalists sound alike, but i still say the dude from Hassan I Sabbah had something unique going on. CTTS' vocals are sweet in their own way

Our options kind of suck as it just seems to be an introduction to screamo up there. Saetia and Orchid? Ew.
With the above choices, big fan of I, Robot and Pg. 99.

Best screaming?

Ahh, so far based off of what I have heard: Bert McCracken from the first cd. I haven't heard their third cd (if it has even came out).

In Maybe Memories, Bert's screaming. Maaan, I think Bert's screaming is hard to beat.

That's why there's "other".

I downloaded Wolves' "Art.Culture.Work".

Sort of disappointed.

I think that's a fun album.

Hey, why isn't everyone voting for The Used? They were totally on that list of cookie-cutter MTV trash bands.

With that logic I'd say Toru Okada.
Good emotion, no squawk.

Normally I'd say Portrait, Pg. 99, or C.O.C., something like that.
But since this is such a difficult question just because there are so many good screamers out there, I'll just list the ones I think use the most technical-precision and out-of-the-box ideas in their vocals:

Crestfallen, Jerome's Dream, The Kodan Armada, Bravo Fucking Bravo, and fucking Takaru.

I Would Set Myself On Fire For You do pretty average vocals for a screamo band that likes to have normally sung melodic lines, but they get props for passing the vocals around in a 3-person circle mechanism, that's pretty tight.
