James Kalyowa, commonly known as Genius Omuzira, is a Ugandan rapper. 

He is one of the top Lugaflow artistes in Uganda, and basically recognised for his unique wordcraft and mature lyrical content.

He was born on January 20, 2000. Luweero

His passion for music started earlier when he was just a kid who used to sing for his father after some coins, and his mother was a music trainer of Traditional Development Association (TDA) choir, from whom he got the big desire of becoming a musician.

He got a public eye from his first song "Twandibaddeki" which he released in 2019 as he allocated Ugandan musicians each one to a profession, had they have been if not joining the music industry. And it was produced by Brian Beats.

Behind his name, he goes by a moniker of "King Jemcee" and this one came after his given name James when he wanted to relate it to his career of being a rapper (emcee).

As a way of combining James to Emcee, he got a phonetic result "Jemcee" and the title "King" is just an additional to make it persuasive.
