February marked the 40th anniversary of the Iranian revolution, a time of fundamental change for Iran. Women had played a significant role in the revolution but in the aftermath and the ensuing years, they saw their rights and position in society restricted. In a special episode for International Women’s Day, this week’s Music Planet Road Trip comes via Persian singer and advocate for freedom of musical expression, Mahsa Vahdat. Get ready for soaring voices and century-old archive recordings from pre-revolution Tehran as Mahsa takes us on an inspirational musical journey with the women of Iran.
