On today’s show: 

• Indian Prime Minister Narendra Modi will address Congress this week. It follows his meeting with President Barack Obama. We unpack the issues they covered, and what impact it will have on the global fight against climate change.
• We talk with photojournalist Emmanuel Guillén Lozano about his exhibit opening in Chicago. It’s called 43: The Portrait of a Disappearance and documents the lives of families of 43 disappeared students from the state of Guerrero, Mexico.
• When it comes to 1970’s rock music, Nigeria probably isn’t a country that comes to mind. But Nigerian musicians were churning out the sounds of that decade, too. We take a look at the country’s place in rock and roll history.
