Professor Jay, is a Tanzanian hip hop artist. He is one of the prominent representants of the "Bongo Flava" Tanzanian hip hop subgenre, which mixes elements from both Western hip hop and the Tanzanian tradition (including swahili lyrics as well as an activist attitude towards Tanzanian social issues such as HIV/AIDS, wealth, inequality, and political corruption).
He started rapping in 1994 as a member of the group Hard Blasters, best known for their hit "Chemsha Bongo" (then he used stage name Nigga J) from their first album, "Funga Kazi". Only one year later, they won the title of best hip-hop group in Tanzania.
During his solo career which he started in 2001, he has released number of hits, including "Nikusaidiaje" and "Zali la Mentali (feat Juma Nature)". Other songs released by Professor Jay include "Piga Makofi" and "Yataka Moyo". Just like Mr. II, he is a pioneering Tanzanian MC, who have remained some of the most popular hip hop musicians in Tanzania, despite influx of many new bidders. Also similar to Mr. II his lyrics often have political messages. In one of his songs he imitates an elder politician and ridicules the fake promises they all mindlessly spew as they are trying to get elected. The song continues with a chorus saying the words "Ndio Mzee" which means "Yes Elder". This represents the brain washing of the public as politicians make these false promises over and over. It is interesting to note however, that after this song was produced, the president of Tanzania referenced the lyrics in one of his speeches, which acknowledged the presence of Bongo Flava and the success of Professor Jay's political lyrics. His first album, "Machozi, Jasho na Damu," gained instant recognition for which Professor Jay won several awards. He attained other awards such as the best hip-hop album in Tanzania with his second album, "Mapinduzi halisi".
