Ver Cuevana2. A documentary that shows us a world of authentic American music inside Brushy Mountain Correctional Complex in Tennessee that has never before been seen by outsiders. In preparation for a live album, Nashville singer-songwriter Mark Collie and a film crew roamed the vast expanses of Brushy Mountain for months meeting inmates, many of whom are talented singer-songwriters. It is the remarkable stories of these talented inmates and their awesome musical performances that give the movie its extraordinary power.
