There are hundreds of streets in the US named for Martin Luther King Jr. A documentary film called "The MLK Streets Project" looks at what life is like on those streets, and what that says about Dr. King’s legacy. We talk with one of the filmmakers. Then, we talk with Sean Michaels, author of the novel “Us Conductors” about the inventor of the theremin, a musical instrument you play without touching. Plus, George Collins, who was editor-in-chief of Baltimore’s Afro-American Newspaper and a WMAR broadcaster, died last July at age 88. We talk about Collins’ coverage of the civil rights movement in Maryland with his colleague, Charles Robinson of Maryland Public Television.
