In 1993 Nii founded Frititi - meaning ‘ancient’ in Akan (Ghana). This London-based performing arts company focuses on maintaining close contact with genuine traditional styles. With Frititi, Nii began to share his extensive knowledge and wisdom by touring, performing, and teaching across the world. At a time where the frontiers of the world were opening with more and more people looking to Africa, Frititi became a torchbearer for traditional culture upheld by gifted dancers and musicians. For both performers, learners and audiences alike, the company holds a sense of exceptional quality in its dedication to expand and explore different repertoires in homage to the great spirit of African music and dance. His work branched into Asia in 2004 when he first set foot in Singapore. In 2019 Nii founded Frititi's sister company Sankofa Singapore through which he performs and teaches, working in collaborations with like-minded local individuals, groups and companies.

As well as percussion, hand and kit drums, Nii also plays the balafon, flute, and sings. He's performed internationally with world music chart-toppers including Osibisa, Konkoma, Baka Beyond, African Headcharge, and Lorraine Ayensu, as well as different incarnations of his solo band. His music is rooted in the traditions he's spent a lifetime exploring. As the Gold Coast meets the distant shores of the English channel, his is the sound of a new generation weaving together the sounds and stories of the places he has been and the powerful messages that nature has to give us. His live presence on stage is electrifying as he pays tribute to his ancestors in sound, movement, and spirit. 

Nii's extensive knowledge of African music and dance is met by his unique and accessible teaching style and he continues to spread his great love of the culture as far as he can.
