Belle Ehresman AKA Bellatrix comes from a musical household - she studied music and plays the double bass - but she became a professional beatboxer by accident. She has just returned to the UK from the 2015 World Beatboxing Championships with a 'crew' battle title to add to her solo wins. However, Belle is re-thinking her views on whether the separate male and female competition categories should be integrated, because she believes that there are gender differences in beatboxing styles which should be celebrated.

Swiss rapper and beatboxer Steff La Cheffe loves how "bossy" her stage-name sounds. In real life she is Stefanie Peter and hails from Bern in Switzerland. Her brother gave her a CD by Rahzel when she was 12 years old and her obsession with beatboxing has never gone away. Stefanie is famous for her ability to produce deep bass notes and says her mission is "to surprise and irritate people" with her performances.
