Hybrasil learned his craft working as a house engineer at Temple Lane and Grouse Lodge Studios, where he recorded and produced music on NEVE and SSL Consoles across genres such as Blues, Jazz, Folk Music, World Music and Prog Rock. After many years of honing his skills as a sound engineer with a variety of different artists from different backgrounds, work on the Hybrasil live and studio project began.

In 2005 he took up residency as a radio DJ, presenting a late-night 3 deck mix show inspired by The Wizard on WJLB Detroit. It wasn’t long before Hybrasil was picked up by Irish National Radio. A broadcasting career that eventually spanned a total of twelve years.

The Hybrasil live project debuted in 2016. What followed was a series of digital/vinyl releases on his own eponymous label and a number of key performances at festivals and clubs across the continent. His most ambitious project took five years to develop. For this, he wrote a live show entitled ‘Spaces’, performed before Jeff Mills & the National Concert Orchestra at Dublin’s Bord Gais Theatre.

Shortly after moving to Berlin in 2018, he was welcomed into the Rekids family by Radio Slave, debuting on the label with the ‘Afra EP’ and his debut album ‘Embers’. Since joining the label he has picked up a number of mix credits on Rekids as well as embarking on an audio visual collaboration with Tom Hodgkinson of Bristol based design studio ‘Shop’, which has featured on key releases such as We Don’t Flip (Rekids), Dezik (Awesome Soundwave) & Tuatha De Danann (Rekids)

Matt Edwards

In 2006 Matt Edwards set in motion a movement that would creep deep into the cracks of the underground techno and house scene. Driven by determination and guided by innovation, Edwards would shape Rekids into one of the most prolific and respected labels of the coming decade – and beyond.

With a proven track record for realizing artistic potential, Matt, perhaps better known as Radio Slave, has been driving talent to the forefront ever since. Some of the industry’s biggest influencers and style icons have emerged from the Rekids vision. Artists like Nina Kraviz and Peggy Gou, whose music caught the ears of Matt and Rekids. In fact, it was Rekids who hosted Nina’s first live show in Rex. Mr. G and his genre-defining album ‘Retrospective’ found a home on Rekids alongside quintessential releases like SRVD’s ‘ELEVATE’, Radio Slave’s “Feel The Same’ and of course Nina’s ‘Ghetto Kraviz’, all of which have become synonymous with and contributed to the spirit of Rekids.

Diving into the back catalogue is like a techno encyclopedia, Carl Craig, Kenny Larkin, Gerd Janson, Chris Liebing, Speedy J, Rodhad, Len Faki, Mike Banks (Underground Resistance) and many more have all released music under the Rekids banner, gaining a highly devoted following. Residencies in iconic techno havens like Rex and Panorama Bar and showcases on multiple continents continue to inspire and spread the Rekids energy worldwide. It’s no wonder why or how Rekids got to where it is today, hard work defined by dedicated principles and a talent for artistic vision tends to attract success, however you measure it.
