Possibly the most inspiring audio I've ever heard. It's literally just a 6 person performance.
It features Neil Patrick Harris, Lawrence Pressman, Josh Radnor, Ron Rifkin, Patricia Wettig. They all play 2 characters, and because of the lack of visuals, it's a seamless show of talent. You probably know both Neil Patrick Harris and Josh Radnor from "How I Met Your Mother", but don't be dissuaded by the cheap comedy from that show. This is a world class show and it speaks to the heart and puts things that would otherwise never be verbal into dialogue.
It makes you feel depressed and hopeful at the same time. In just 2 hours, you are on a rollercoaster of emotion brought on by political allusions and powerful romance. I reccommend it to everyone, but you have to find it first.
