Reaction Bike-Power Stage

Expect big sounds from the Reaction Bike-Power stage. This is a truly people powered stage featuring the mighty Reaction Sound System.



The speakers are 100% people powered using 9 bike generators pedalled by YOU! The cyclists have to work together to keep power levels high – the harder you pedal the louder it gets! Reaction use their custom built solar rig to power the lights and keep the decks spinning, resulting in fossil fuel free, full eco-vibes.    

This year they have expanded their horizons and as well as the customary roots, reggae, dancehall, dub and jungle from the Reaction Crew, they’ve invited a selection of their pals to bring you reggae, rockers, roots, calypso, ska, dub, funk, cumbia, afrobeat and disco – combining to give you some serious aural pleasure

Kaya Arise


Kaya Arise is a selector and host out of Guildford, touching the mic to bring a soft edge to a deeply rootical vinyl selection. Her inspiration is encouraged by Reggae music from the 1970’s to an instrumental melodic style of dub now. 

Sparking from experiences of exploring the UK free and festival scene, to meeting veteran sound system Rebel Lion in Norfolk, Kaya eventually found solace in Reggae/Dub music in 2011. With the push of collective Sisters of Reggae and Stack UP sound to learn and DJ across London, Kaya began her own platform Arise Music in 2018, travelling wide in the UK, as far as Brazil to select/MC. 

In 2019 Kaya hosted several sound system events and curated the Feminine HI-FI tour in London, followed by an explorative discussion on themes related to race reggae and culture online in 2020. Forward into 2021 Kaya is learning how to produce her own music with guidance from mentor’s as well as, writing for DJ Mag on Reggae and working at her local community radio station Kane FM.


Ms Fabulous

DJ-ing on for over 10 years, mainly with Irie Vibes sound system based in York. I love to mix up the styles and decades of reggae, and in my set I go from Calypso and Bluebeat to dancehall and mash-ups, taking in ska, rocksteady and roots along the way. I love a version excursion, but most of all I love a good melody and sweet vocal harmonies or a mean bit of toasting.

Being One (aka Castrum)


Being One’s entry into the world of events came with a video camera, starting Castrum Productions in 2009. In 2011 he was introduced to Soundsystem culture, at a Pressure Roots HiFi night in Falmouth and since then, he’s never looked back.
He discovered that setting up the event required less processing power, which has led him to finding a local sound to help wherever I go. Over the years he has helped: Pressure Roots HiFi, Rig Smith HiFi, Black Cat Soundsystem, Roots Guidance Soundsystem, Unit137, Instrument Of Jah Soundsystem, Jambeater Soundsystem, Unity Sessions HiFi, The Drop Soundsystem, Ring The Alarm Soundsystem, Reggae Roast Soundaystem, Urgent Union Soundsystem, Bushrocker HiFi, Reaction Sound System, Caya Soundsystem, Channel One Soundsystem, Island Report Soundsystem, Creation Rebel Soundsystem, Mawashi Soundsystem, Scorcher HiFi and Pressure High Soundsystem to name most so far. 
Being One has been selecting and collecting over the last 5 years around the UK, Europe and moving around New Zealand and Japan over 2019/20.  Since returning I have been hosting the Musical Monday show, each and every week on Rootsyard Radio Studios Mixlr station (, streaming all over the world.
Be sure to look out for Being One, as we spread positive vibrations of roots, reggae and dub, to heal the nation.

So get ready to be hit hard by the bass and taken on a clubwise journey by the drums, to explore the space where the rhythms of the Caribbean’s meet the spaciest depths of UK bass music.
