 On the next Echoes, music from New Age diva, Maria Stark. She teams up with multi-instrumentalist Daniel Berkman. He plays kora, cello, and on domo, an electronic keyboard based partly on Lyons-Martineau. I'm John DiLiberto. Their album is Underground River, and it flows into the next Echoes from PRX. Wednesday night at 10, here on 90.5 FM.
