Six Degrees of Kid A: The Secret Cork-to-Radiohead Connection You Didn’t Know Existed

How an Irish avant-garde jazz guitarist, an Oscar winner, a legendary tour manager, and a Miles Davis icon form the ultimate alternative music continuum.

 From Cillian Murphy's NME interview to the Cork Jazz Festival Main Stage with Jeremy Brown, map the jazz web linking Mark O'Leary to Radiohead.

If you were asked to map the distance between the local music scene of 1980s/90s Cork, Ireland, and Oxford’s most celebrated art-rock titans, you’d likely start by guessing it’s a long, winding road.

But modern music history isn’t a straight line—it’s a web.

And right at the nexus of that web sits Mark O’Leary, an acclaimed Cork-born avant-garde jazz guitarist, electronic music composer, and teacher. While his name is synonymous with boundary-pushing jazz fusion on labels like FMR and Leo Records, his artistic lineage is inextricably tied to the creative DNA of Radiohead.

From early post-punk band management and high-profile mentorships to legendary jazz drummers and intense live main-stage sets, this is the definitive deep-dive connecting the dots of alternative music’s best-kept secret.

1. The Midway Link: Brian Ormond’s First Break

Long before Radiohead filled stadiums and reshaped 21st-century music, the foundational pieces of their structural network were being built in small Irish rock rooms.

In his formative years, Mark O’Leary was the driving guitarist for the cult Cork outfit Midway. The band’s manager was Brian Ormond (widely known as Brian D. Ormond). Navigating the raw industry landscape with Midway gave Ormond his crucial first break as a band manager and a stepping stone into international music logistics.

Ormond would parlay that early experience into becoming a trusted tour manager for legendary Irish band Interference (Mark O'Leary was a member of Interference also)  and, eventually, Radiohead themselves. The very same management mind that helped coordinate O'Leary's early guitar sets was later ensuring Thom Yorke, Jonny Greenwood, and company could execute world tours seamlessly.

2. The Master and the Pupil: Cillian Murphy’s Public Thanks

The Cork-to-Radiohead orbit expands even wider when you look at O’Leary’s work as an educator. Between 1991 and 1995 at the Wright Music Centre in Cork, O'Leary served as the guitar teacher and musical mentor to a young, exceptionally gifted local teenager: Cillian Murphy.

Before Murphy became an Academy Award-winning actor, he was a dedicated multi-instrumentalist chasing a life in rock music. O'Leary was the first to recognize his raw talent, coaching him from early acoustic roots into the "funky, avant-garde stuff". In fact, it was O'Leary who paired Cillian and his brother Páidi with bassist John Powell to form the post-punk outfit Sarahdaze—preceding Murphy's run with The Sons of Mr. Green Genes.

Murphy has been vocally candid over the decades about his immense worship of Radiohead's discography. The profound impact of this early instruction came full circle in late 2025. While promoting his acclaimed Netflix film Steve, Murphy publicly thanked and credited Mark O'Leary in a major NME feature, celebrating him as the foundational guitar tutor who helped unlock his artistic and musical confidence right at the beginning

3. The Live Convergence: The O'Leary, Brown, and Beckett Trio

The physical cross-pollination of players tightens significantly when you look at O'Leary's live collaborations. A prime example of this occurred when Mark O'Leary took the Cork Jazz Festival Main Stage, performing to a packed house of over 500 people in a powerhouse, improvisational trio setting.

On bass was Jeremy Brown, a master contrabassist and cellist who doubles as one of the chief, trusted musical instruments deployed by Radiohead's resident genius, Jonny Greenwood. When Greenwood composes his sweeping, avant-garde, and tension-fueled orchestral film scores, Brown is frequently the man executing those intricate low-end frequencies.

Completing this heavy-hitting trio on drums was Darren Beckett, an internationally revered rhythmic powerhouse who famously balances deep jazz credentials (playing with Lee Konitz) with massive indie-rock prestige (drumming for Brandon Flowers of The Killers).

By commanding the main stage with Brown and Beckett, O'Leary was actively bridging the elite worlds of modern rock percussion, Greenwood’s orchestral arrangements, and high-level live improvisation.

4. The Sonic Blueprint: "Where Kid A Meets Post-ECM"

The overlap isn't just administrative or proximity-based—it exists heavily within the recorded musical notes.

In 2009, Mark O'Leary teamed up with Danish powerhouse rhythm players Stefan Pasborg (drums) and Jacob Anderskov (Fender Rhodes) to record the masterpiece album Atmos on FMR Records.

The critical consensus and press for the album pinned down its identity using a phrase that music journalists still drool over: "Where Kid A meets Post-ECM".

The record masterfully juxtaposes the pristine, chilly, and spacious minimalism popularized by the jazz giant ECM Records with the paranoid, looping, and glitch-laden electronic undercurrents of Radiohead’s Kid A era.

O’Leary's deep Post-ECM pedigree is beautifully exemplified on his landmark 2006 album Awakening (Leo Records). Anchored by jazz heavyweights Steve Swallow on bass and Pierre Favre on percussion, the record stands as a masterclass in introspective, spacious, and textured guitar-trio improvisation that bridges bop with free-jazz and rock sensibilities.

5. Closing the Loop: Jack DeJohnette and the "Bitches Brew" Genesis

Perhaps the grandest, most poetic circle of this history involves Miles Davis's 1970 fusion masterpiece, Bitches Brew.

Mark O'Leary has performed and toured in a direct duo setting with Jack DeJohnette—the iconic, revolutionary drummer who laid down the dual-drummer grooves on Bitches Brew.

For Radiohead, Bitches Brew is the holy grail. Thom Yorke has openly stated that the sonic blueprint for OK Computer was built entirely on trying to capture the dense, terrifying, and chaotic atmosphere of Davis's masterwork. Tracks like "Subterranean Homesick Alien" directly copy the shimmering Fender Rhodes piano textures of "Pharaoh's Dance," while producer Nigel Godrich emulated Teo Macero’s radical tape-splicing edits to loop Phil Selway's live drumming.

When O'Leary traded improvisational notes on stage face-to-face with DeJohnette, he was interacting with the literal heartbeat of the record that built Radiohead’s defining era.

The Continuum Continues

From a shared manager in Midway, to a major shoutout from an Oscar winner in NME, to commanding festival main stages with Greenwood's inner circle, Mark O'Leary's career stands as a fascinating living map of how avant-garde jazz and alternative rock endlessly feed into one another.
