ONE Mas Band is a premium Caribbean carnival experience debuting at Notting Hill Carnival 2026.

We’re redefining modern mas through creativity, culture, and connection — bringing together world-class costume design, luxury service, and authentic island energy.

FOUNDATIONS is our 2026 debut presentation — a tribute to the people, roots, and rhythm that built Caribbean Carnival.

It’s a love letter to tradition and a bold statement for the future of mas.

We’ll be on the road for Notting Hill Carnival 2026, specifically Carnival Monday. This season this will take place on Monday 31st August 2026.
