I think you are talking about a combination of several specific traits often found among females especially covering the classic rock and blues genre's, yet as you mention males too. It's VERY common in Operatic vocals too.... I think one of the features you are describing is called "Belting". The other is a higher headier larynx pushing that is dangerous.. While today I hear more commonly term mezzo-sop used, this wasn't heard of in rock days when I was younger, the term in those days I believe was referred to as "Chest Belt Tenor voice" and when I questioned women I was working with about the term that was used among females I worked with in the 70's "Chest Belt Tenor", she'd never heard of it.. Today I think some Mezzo-sop's use this...I can't imagine what Kate Bush did to her voice in the 1980's :/ OUCH....as a soprano doing that...ALot of larynx pushing... That would sound like screaming I assume if it's generated from the throat, and not the gut... I think the gut sound is called belting tho... Jazzy and Jason would likely know this stuff..
The high output ball's to the wall belting was probably similar to the rigor's of the physical and emotional stress the Operatic tenors, and female rock vocalists put themselves thru when covering some of the classic rock and blues songs.. and trying to use their larynx, diaphragm, and even sinus cavities to overcome certain venue's and instrumentals... High energy rock vocalists did this all the time.. Most ended up talking like Rod Stewart and Joe Cocker, yet this was also a means of breaking into voice Gravel... Sort've like singing from your gut in order to transcend the limitations of your throat....
VERY VERY dangerous ! It's tremendous stress on the throat and larynx.. Broadway actor's and actresses often end up doing that type of thing too....
The style I believe is known as "belting", yet it often integrates tremendous voice-box straining too....
I don't sing, I'm just the instrumentalist that hides behind singer's, write's arrangements, and has written for, and directed glee clubs at many levels...and worked with barbership and mens glee
Bass, Bari, 2nd, 1st, and falsetto voices..
as well as women's glee clubs.. including the soprano voice registers...
I'm just a wannabe singer... Yet have had to study aspects of vocal's to work with you folks, before you replaced me with Karaoke tracks..
