Kemba is a collaborative project between Matthew Jefferson (born November 21, 1990), the rapper formerly known as YC the Cynic, and producer Frank Drake, but the name is also used on occasion to refer to just the former.

Jefferson is a rapper from The Bronx. On his 2013 release GNK, he first collaborated with Frank Drake, still under the name of YC the Cynic. Their collaboration was given the name of Kemba when Jefferson and Drake released The New Black Theory in 2016, the first single from their upcoming album, Negus. The album was released later in 2016, with the two artists collaborating on every track.

Kemba was unsigned at the time, relying on a Kickstarter campaign to finance GNK, their first collaboration.

Kemba is currently signed with Republic records with the release of his 2019 album Gilda.
