Query: ugly twanging guitars constantly playing in the background

I looked forward to watching the program on PBS but after half a hour I turned off the TV and went to bed. Why? The program that could have been marvelous was completely ruined for me by the incessant background noise, ugly noise, of twanging guitars playing on and on and on and on and on, even when people were speaking. It was so obnoxious and my relief was so great when, for a short while, the noise stopped, that I decided I simply couldn't take it any longer and turned off the TV. If somehow you could keep the narration and get rid of the background noise the program would be fine. But I am sure that can't be done.
