Choose your own sound – a vocal close up

Some singers are «the less I know - the better I sing» people - and I love them for it. One of my favorite singers in Les Miserables was like this. He just sang, and sang - so breathtaking and wonderfully night after night with great success and to standing ovation. Though, every time somebody asked me about a vocal chord issue or like best vowels for belting, he just ran from sight, like it already was the third battle in second act.
