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.
The negative effects of combat were nightmares and I'd get jumpy around certain noises and stuff but you'd have that after a car accident or a bad divorce. Life's filled with trauma. You don't need to go to war to find it it's going to find you. We all deal with it and the effects go away after awhile. At least they did for me.
