Chicago Reader music writer Peter Margask stops by Radio M with some new releases. It's the third Friday of the month, and that means another edition of New Sounds with Peter Margasak. This month Peter's picks include Ukrainian a capella by way of San Francisco. Also a conversation with Marie Daulne, the founder of Zap Mama. For almost two decades, Zap Mama has mixed African, European, Middle Eastern vocal traditions with a dose of American soul and Fela Kuti style afro-beat for an intoxicating sound.
