Wasaza Isa (born 16 August 1998) is a Ugandan rapper and songwriter known by stage name Kalma.

Started a music career in 2019.

At a young age, poisoned and caged by the history of his surrounding. Music gave him “Family” beyond family. Love, peace, unity as blood that ran through him. Mistakes, anger and tears as our road to it. 

In the slums of Kampala he commenced his musical journey with street and small gathering performances. A platform he manipulated to preach how society has nothing to do with ones dreams. 

He recorded his debut single "come home" where he reached out to all the loved ones in the covid-19 pandemic, giving them a reason to smile again.

He later on added on with other hit singles like down life, cow ride, and why where he highlights the Ugandan street life, family and love.
