Well Jeff Buckley for me is one of the greatest singers I've ever heard. And the reason why is he has an amazing range amazing emotional power in his voice. And the music he put around it also just had this passion and this soul to it and this spirit to it that very few artists have and he passed at a very young age.
Solitude can be used well by very few people. They who do must have a knowledge of the world to see the foolishness of it and enough virtue to despise all the vanity.
