Saturday night marks the third annual Yelloween celebration in downtown Yellow Springs. Organizer Brother Bear visited the WYSO studios to chat with Niki Dakota about this year's event, which has a sci-fi theme. The celebration will feature live music from the Coffin Daggers, a New York-based surf punk band with a sci-fi twist of its own, that also stopped by the WYSO studios to share some music ahead of their live performance.
