Armstrong Kalua (born April 29, 1990), professionally known as Onesimus Muzik, is a Malawi-born Afropop singer and songwriter.

He discovered his knack for lyrics in 2008 when he joined the rap group Blessed Beyond Measure (also BBM Clique) dropping tracks such as “By MySide” and “Random Thoughts” with the outfit. The artist was to venture into a solo career soon after, working on an unreleased hip-hop mixtape called “Beyond Limits” for a year in 2009 before he found his true calling, music. Onesimus started singing secular music in 2010 and finally released two singles: “Beautiful” featuring award-winning Malawian rapper Young Kay and “Without Your Love” which landed him a coveted deal with the record company ‘Nde’feyo Entertainment’. Almost instantly thereafter he began his tour in Malawi, in 2011.

Onesimus dropped a R&B mixtape titled ‘BRB’ in 2012 and - in the same year - dropped his debut Afro R&B album: “Ndele”. In this album he showed his diversity as he also sings in his mother-tongue - Chichewa. By this time he had already worked with several of Malawi's urban music icons and also did a song called “Musiye Ayende” with Zambia's musicians Dalisoul and Afunika. He made appearances on many line-ups at acclaimed music festivals in Malawi sharing stages with the continent's industry giants: Oliver Mtukudzi, Freshlyground, Salif Keita, Professor, AKA, Naeto C.

In 2019 he won Best Male Artist at the African Inspirational Music awards ceremony. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
