Chris Rob is the younger brother of the Office star Craig Robinson. The Robinsons grew up on the South Side where they were taught to play music by their mother, who was a music teacher at Whitney Young high school. Now Chris Rob is a pianist, singer, songwriter and producer who’s played with the likes of Anita Baker, John Legend, Kanye West and Stevie Wonder. He stopped by the studio Friday before playing at the annual Supreme Love concert at the DuSable Museum over the weekend. (WBEZ/Kathy Chaney)
