 On the next Echoes, we talk to Rich Ruth. That's the performance name of Michael Ruth, a multi-instrumentalist from Nashville. His music is a flow from ambient to free jazz. His new album is Water Still Flows. I'm John DiLiberto. Join me with Rich Ruth on Echoes from PRX. Monday night at 10 here on 90.5 FM. Coming up on 5 minutes past the hour, you're listening to Jazz Sunday on WCBE.
