Tanya Morgan, as the title of one of their mixtapes states, is a rap group. Von Pea and donwill have been putting out classics since their 2006 debut Moonlighting. They’ve gone through successes, failures, lineup changes (original member Ilyas left in 2012), and more while continuing to reach for new sounds and concepts. Their most recent release is the EP 12 Minutes at Karriem’s. We talked to the group about touring disasters, childhood friendships, Google Maps, that time donwill almost ended up on Cops, and much, much 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.

Molly Melching first went to Senegal in 1974 as an exchange student from the University of Illinois. But, instead of returning to the United States, she stayed on, eventually creating a nonprofit organization to educate and empower women and communities. That organization Tostan created and implemented educational programs focused on human rights, health, literacy, financial management and childhood development. It may be best known for leading thousands of communities in Africa to end female genital cutting and forced childhood marriage. WPSU's Anne Danahy talked with Melching about her work.
