For more than two decades, John O’Callaghan and Bryan Kearney have stood among the defining figures of modern electronic music. Built on a lifelong friendship and a shared desire to push creative boundaries, their partnership eventually evolved into KEY4050.

Long before the project officially began, the pair spent countless hours writing together in a modest apartment on Dublin’s Meath Street, unknowingly laying the foundations for one of electronic music’s most distinctive collaborations. Even the name traces back to those early days, combining the apartment’s security code, 4050, with the musical “key”.

Launched in 2019 with the ambitious 32-track debut album Tales From The Temple, KEY4050 immediately established a sound that refused to recognise traditional genre boundaries. Blending cinematic electronica, techno, breakbeats and peak-time club music, the project has released music across Black Hole Recordings, Armind, Kearnage and Subculture, including defining records such as “I Love You” featuring Plumb and “Cisza”, the official anthem for Dreamstate Europe 2022.

On stage, KEY4050 has become a fixture at many of the world’s leading electronic music events, including Tomorrowland, Transmission Prague, Dreamstate, A State Of Trance Festival, ASOT Mexico and headline performances across Europe, North America, Asia and Australia. Their appearances at Luminosity Beach Festival, where they closed the event in both 2022 and 2026, have become defining moments in the project’s story, reflecting their ability to create experiences that resonate long after the music ends.

The next chapter begins with the release of “Empty Space” in August 2026, leading into the second KEY4050 album, Stay In Your Lane, arriving in January 2027. Driven by instinct, friendship and a fearless creative vision, KEY4050 continues to redefine expectations while creating music that connects, challenges and lasts.
