The Evolution of the Male Falsetto

This means a vocalist needs to get in the upper register to have sonic space.
Some of the best rock vocalists of all time, for example axl rose and Chris Cornell, are actually low baritones singing almost exclusively in an idiosyncratic blended falsetto.
Related: pre distorted electric guitars, baritones were considered the most attractive in pop music... Elvis was a tenor who sang in the baritone register, I believe.
I'm not sure where the debate would lie; falsetto is a clearly identifiable physical voice register that, without deliberate training, sounds quite different from the usual 'modal' voice. Futhermore, there is generally no 'in-between'--it's either one register or the other. Some singers can switch between the two without audible seams, but it's very difficult.
Actually, Led Zeppelin are not metal. And it's strange to read an article that praises male metal vocalists for their falsettos without even a passing mention to the indisputable god of all metal falsettists, gay and straight alike, whose name I don't even have to actually say. He is that conspicuous by his absence in that article.
Oh, alright. I mean Rob Halford. Who writes an article about falsetto vocalists and leaves out the man who sang this?

Here it is sung by Dimash Kudaibergen, a 25 yo Kazakh:

He is university trained in classical as well as in contemporary music and is known for his wide vocal range of 6 octaves, from D2 to D8 (and 6 octaves and 5 semitones, from A1 to D8, with vocal fry). This spans from the bottom of the bass range beyond the top of the soprano range.

You can hear more typical range in the first half of that video.

Singing with too much falsetto is annoying; it should just be used to reach a few high notes, IMHO. If someone has to falsetto the whole song, it's in the wrong key or register for them.
In the 1970's, supposedly, radio stations used to advertize "Bee-Gee-free weekends", ha.
