OSB

It all began in the 1990s in Plaisance, Rose-Hill, where a group of young urban dance enthusiasts decided to take their artistic expression to the next level. Led by Bruno Raya (Master Kkool B), his brother Kenny, and Jérôme Chamtyoo, they founded Otentik Street Brothers (OSB) — a collective that would go on to become a major reference in the Indian Ocean music scene. Over the years, iconic artists such as Jean-Clario Gateau (Blakkayo), Pascal Ferdinand (Dagger Kkila), and Kensley Lafolle (Tikkenzo) joined the group.

OSB quickly evolved from street performances to the studio, delivering powerful lyrics over beats influenced by Jamaican genres like ragga and dancehall, blended with distinctly Mauritian elements such as séga and, most notably, seggae. This fusion gave birth to a unique style: Creole raggamuffin, deeply rooted in reggae and seggae culture.

Driven by a strong social commitment, OSB has always used music as a tool for awareness and mobilisation. Their lyrics speak truth, challenge injustice, raise consciousness, and bring people together.

Today, Otentik Street Brothers represents more than just a musical genre. It’s a movement, a living legacy, and a cornerstone of Mauritian urban culture — a voice from the streets that has reached far beyond the island, all the way to prestigious stages like the Summerjam Festival in Germany.
