Mazbou Q

aka The Rap Scientist, Unchained XL, Hugh Ozumba


Mazbou Q draws from many styles of music. Under his former moniker, Unchained XL, he made Afrobeat-inspired hip hop, which is still central to his sound, but Mazbou Q’s music now extends all the way from sparse, synth-driven beats through to the funky tracks performed live, and modern hip hop sounds of drill and trap. Mazbou has also turned his knowledge of rapping into an incredibly popular social media channel.

The man behind the raps is Hugh Ozumba, who started his career in metalcore band East of Eden. The band inadvertently started when he and his teen friend Spencer Jones got together to record a few demos with no aim in mind. They put a song online and were surprised when people offered to join their band.
