Kelly Jones from Stereophonics technique to sing quite soft ?

Hi !
I've listened this morning to a version of "Don't Let Me Down" sung by Kelly Jones and what surprised me is his abbility to sing the "Don't Let Me Down" thing with little volume.

How can you sing with such control, low volume, what can i learn from him ?
Thank you by advance !

He's just adding textures to his voice to make it sound gritty.
