How can I sing through a P.A system to backing tracks and hear myself and the backing not through speakers but through headphones?

No. In fact that might do damage to your vocal chords. You just have to gradually stretch your range in an appropriate fashion.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
