According to Craig, 70, a long time prisoner, Prisoners Listening to Music is not scary...

You don't understand nothing. They're not dying. They're gettin past their hungers. It's the music that makes them pure, like angels. Listen, when I was young down south, we had a chaplain. Every day he would play music for us. Old music, beautiful. At first we couldn't listen to it. We never heard nothing like it. Sometimes a song would last a long time, no words. But then we started to love it. We would listen like in the picture, and we'd remember things. And we'd cry. Sometimes you could hear ten men cry. And sometimes the priest would cry too. We were all together in it. But then he retired, and a new chaplain came. He was different. He wanted us to see the doctors and counselors, the case workers. They would ask us questions about ourselves and make us go to classes, programs. They were working on us, and the music ended. It was different. It was us against them.

Howard Zeiderman, founder of the Touchstones Discussion Project, quoted Craig in an essay called The Hunger for Control - Caged Explorers (could only find a .pdf; sorry).  Kathe Kollwitz drew the picture.  And I clipped it out of a Touchstones textbook.
