Just another article or story to fill space. However, I find it intriguing that Steve Marriott... more or less a forgotten name at this point in rock and pop culture, is one of the five mentioned.
As for Bowie... Ocasek, Byrne, etc... the MSNBC writer views personas or characters as insincere while I view them as an extension voice, a fiction that can voice heartfelt truths. The equivalent with acting is that Anthony Hopkins should only play characters that resemble himself, that is, an actor playing an actor, not, say, Hannibal Lecter. Why must singers voice only personal truths while actors have free reign? I never have understood that division.
Admittedly, there are listeners who can't differentiate between character and artist. Once on a lengthy drive from a concert, a friend pointed out a lyric by Eno, saying that Eno must have been an emotional wreck when writing the personal lyric, at which I quickly countered that nothing Eno sings can be taken as a personal voice, not when songs are titled "Burning Airlines Give You So Much More," "The Paw Paw Negro Blowtorch," and "Baby's On Fire."
To me, a musician who goes into character more than once or twice loses his personal voice. They become storytellers no matter if the narrative voice uses the personal pronoun.
That said, I have always viewed Ocasek and Robert Palmer as personal narrators, that is, if you will, singing from the heart. Byrne, in contrast, is more complex, even back at the beginning of Talking Heads. We all know he wasn't really a "psycho killer," but other lyrics were autobiographical with a personal narrative voice...
