text:  I'm John DiLiberto, and you're hearing Echoes from PRX. I've got music by David Arkenstone today. We'll hear a couple of tracks off his album, Quest for the Runestone. I've also got music by Ryan Farrish. He's an electronic artist who started in Christian music, moved into age, and now makes what he calls positive chill-out music. It's kind of EDM-fueled electronica.
