"I'm supposed to be a dead man," says Bobi Wine, a Ugandan musician turned politician. His driver Yasin Kawuma was shot dead on Aug. 13. Wine tweeted a graphic picture he said was of the man's dead body. Wine says police were the ones who shot Kawuma, but Wine says he was their real target. Bobi Wine's real name is Robert Kyagulanyi Ssentamu. He rose to fame as a musician — first with love songs and dance songs, but more recently turned to political themes in his music. His 2017 song "Freedom" has become a rallying cry for the country's opposition. In the same year, Wine was elected to the country's Parliament as an independent. He's become a leader in opposing the country's longtime President Yoweri Museveni — in power since 1986. Museveni is known for violently crushing dissent. Human Rights Watch says the government "continues to violate free association, expression, and assembly rights." "We are living in a country where life does not mean a thing," Wine tells NPR's Scott Simon.

Gangsta Boo joined Three 6 Mafia when she was only a teen. To this day, she is still the first and only female member of the group. After a successful run with the group, she left and embarked upon a flourishing solo career. One of the most active and consistent MCs in the game, Gangsta Boo has worked with some of the South’s best over the course of her career. Memphis born and bred, her sound will be forever engrained in the traditions and classic sound of the city. Honest, hard-hitting, and forever unafraid of her competition, Gangsta Boo has a sound that will continue to be influential for years to come. These days, you can find her working on a new project, Witch, with fellow MC La Chat and producer DJ Paul.

We talked how the Memphis sound is taken without homage paid, the influence of bounce music on her own style, the origins of “get your broke ass out of the club”, some of her most iconic lines, and more.

Joan is a writer who got her start in the 1990s, helping to create what came to be known as “hip-hop journalism” with her articles at places like Vibe and the Village Voice. Whether she was writing about the Mike Tyson trial, profiling TLC, or investigating the sex trade in Jamaica, Joan brought her keen, Bronx-raised sensibility to everything she touched.

Joan pioneered hip-hop feminism—and came up with the phrase “black girl magic,” to boot—in her classic 1999 book When Chickenheads Come Home to Roost: A Hip-Hop Feminist Breaks It Down. And now she has a brand new book, a reflection on Ms. Lauryn Hill’s classic debut album. It’s called She Begat This: 20 Years of the Miseducation of Lauryn Hill.
