Choclair was a high school student in the ’90s when he started spending his nights making hip-hop music with future stars like Kardinal Offishall, Jully Black and Saukrates. Together, they helped grow Toronto’s hip-hop scene into the behemoth it is today, despite limited support from the domestic music industry. Now, at 50, Choclair is setting out with a new album, “Transit Music,” which is his first full-length record in more than 20 years. He joins Tom Power to talk about the record, his climb to success, and the obstacles he faced trying to put Toronto hip-hop on the map.
