 You're hearing Echoes from PRXN. I'm John DiLiberto. Coming up, I've got an artist recording as Discovery Zone. But first, here's Carl Weingarten and Catherine Marie Charlton, a really interesting collaboration from several years back. Carl Weingarten, of course, great guitarist working in a lot of different kind of fields, but mostly modern instrumental music. He's on the West Coast, outside of Sanford.
