Lyndon Stephens, a prominent figure in Northern Ireland's music scene, has died. In a statement shared by his record label Quiet Arch, it was revealed that Stephens passed away on Friday morning, January 10, "following a long battle with illness."

"A techno head, a soul brother, a teacher and mentor, a life-long companion and a father, Lyndon left an irreplaceable impact on all our lives," the statement continued, "and we are unspeakably injured and heartbroken at his loss."

As the founder of Belfast-based record label Quiet Arch, Stephens' artists have won the Northern Ireland Music Prize three out of the last four years – with Ryan Vail and Elma Orkestra's Borders (2019), Joshua Burnside's Ephrata (2017) and Ciaran Lavery's Let Bad In (2016). He'll also be remembered for his work as the founder of Champion Sound Music.

Stuart Bailie is among those paying tribute to Stephens, with a obituary on BBC Ulster's Across The Line blog – praising his remarkable work in transforming Belfast's music industry with Quiet Arch.

"It's the greatest legacy," Bailies remarked in the post. "The back catalogue, the humanity, the pushing away of our cultural cringe, the vast number of personal connections and that singular grace. Lyndon Stephens, you were extraordinary. Fly, on wings of speed."

Deeply saddened by the passing of Lyndon Stephens, the driving force behind @QuietArch, an architect of so much music here, a connector of so many people and above all a beautiful and caring person. My thoughts are with his family and his many friends. A titan and gentleman.
