Tyler is one of the few singers of his generation who never adapted his singing to his age. He just kept singing as if he was still 25. That's commendable in one way, but also asking for trouble.
I don't hear that with modern day Jagger for instance, he paces himself well and has never gone beyond (or to the limit) of what he still can do. He's very good at giving people the "Jagger voice" they want to hear without overstretching himself. And his every economical, but effective vocal technique is underrated. People tend to forget what a proficient singer he is when they marvel at the stage athlete.
He sounds incredibly young, yet not overly vocally processed on the new single.
