Bad things written about me do bother me and affect me, but then I have learnt to take it in my stride. I have also learnt to keep quiet about certain things.
I do the protest stuff. I do country and western. I play both acoustic and electric guitar in a lot of different styles, from loud, psychedelic stuff to quiet finger-picking.
Life being very short, and the quiet hours of it few, we ought to waste none of them in reading valueless books.
Naturally, if I'm singing over really loud music, my approach is gonna be different than if I'm singing over some quiet acoustic music.
