I've had music writer Don Cohen on the show previously, discussing two of his favorite musical genres: Portuguese Fado and Argentine Tango. He joins me again with his latest book, "Gypsy Voices: Songs from the Romani Soul," which collects Roma songs from the Balkans, Romania, Hungary and other parts of eastern/central Europe. We talked Roma history and music while playing tracks (some classics, some lesser-known) from the book's companion CD and doing our best not to overuse the term "Gypsy."
