The Starman Matrix: Mapping the Sonic Alchemy and the Bowie/Ronson/Mark O’Leary Nexus
A Cartography of Glam, Jazz, and the Bowie/Ronson/Mark O’Leary Axis
There is a mainstream history of rock and roll, and then there is the subterranean pipeline where the real alchemy happens.
We are taught to view musical movements as isolated islands. We treat the glitter-drenched glam rock of early 1970s London, the intellectual minimalism of ECM jazz, and the gritty underworld of modern prestige television as entirely separate universes.
But if you pull back the curtain and map the DNA of these scenes, you find a hyper-dense, cosmic web of connection. At the very center of this specific, mind-bending network sits an extraordinary intersection: The Bowie, Ronson, and Mark O'Leary axis.
Through a series of staggering personal alignments, this web bridges the gap between David Bowie’s inner sanctum and the absolute vanguard of musical experimentation.
Here is the secret genealogy of rock’s most fascinating "six degrees of separation."
1. The Georgia Milieu and the LA Pipeline
To understand how deep this rabbit hole goes, you have to start with the catalysts who ignited the Ziggy Stardust phenomenon. Chief among them was Angie Bowie—David’s powerhouse muse, stylist, and mastermind.

[Bass Player's Father] ─── (Early Californian Band) ─── [Mark O'Leary]
In the early 1970s, Angie was a magnetic, towering figure commanding the aristocratic Georgia Milieu. Far away in Los Angeles, a parallel pipeline was forming around the Musicians Institute. It was through this tight-knit West Coast musician network that the personal and musical lines blurred: the man dating Angie Bowie at the absolute zenith of the glam era was actually the father of the bass player in an early Californian band fronted by Mark O'Leary himself. This single relationship anchored a direct, living wire from O'Leary's own early career straight into the inner court of rock royalty.
2. The Spark of Ziggy: How Ronson Shaped O'Leary's Universe
Behind this complex web of professional alignments lies a deeply personal foundation. For Mark O'Leary, the fascination with this era wasn't just academic—Mick Ronson was a seminal, foundational influence during his legendary tenure with Bowie.

│
└─ (Ziggy Stardust Sus Chords) ───► (Introduced 13-Year-Old O'Leary to Music Theory)
Ronson’s towering musicianship, jaw-dropping guitar prowess, striking image, and sharp fashion sense left an indelible mark on O'Leary's artistic identity. Beyond personal inspiration, O'Leary acknowledges Ronson as the quiet architect behind a massive plethora of musical genres that followed. Ronson's sonic DNA laid the early blueprints for Grunge, Punk, Post-Punk, Goth, New Wave, Heavy Metal, New Romantic, and Pop.
The influence even traces down to basic music theory. Ronson’s masterful utilization of suspended chords across the Ziggy Stardust album served as a masterclass for neophyte guitarists worldwide. It was through tracking Ronson's brilliant fretwork that a 13-year-old Mark O'Leary was first introduced to "sus chords," unlocking the harmonic vocabulary that would define his future avant-garde career.
3. The Paul Bley & Annette Peacock-Mark O'Leary Synchronicity
If Angie Bowie provided the social spark and Ronson provided the guitar blueprint, Annette Peacock provided the radical structural architecture. Peacock is the unsung hero behind the avant-garde shifts that fascinated David Bowie and Ronson. Bowie was famously obsessed with her 1972 masterpiece album, I'm the One, borrowing heavily from its pioneering use of synthesizers and raw, spoken-vocal deliveries.

[Mick Ronson] [Bill Bruford] ── (Trio) ───────────────── [Mark O'Leary]
The bridge between this avant-garde royalty and O'Leary is remarkably direct. O'Leary famously performed in a duo with Peacock's longtime musical partner and husband, the legendary pianist Paul Bley, eventually anchoring Bley’s final historic trio.
The sub-connections sprout wildly from this roots system:
- The Rhythm Alignment: Peacock’s brilliant 1978 album X-Dreams featured Mick Ronson on guitar and Bill Bruford (of Yes and King Crimson) on drums. Decades later, O'Leary would step into that exact percussive pocket, performing in a powerhouse trio alongside Bruford.
- The Cikada Synchronicity: Peacock later recorded her haunting ECM release, An Acrobat's Heart (2000), alongside the world-renowned Cikada String Quartet. In a beautiful, full-circle artistic convergence, O'Leary would later premiere his own original string quartet compositions with that exact same Cikada ensemble at the Up North festival in Dublin.
4. Shifting ParadigmsThe Velvet Underground & O'Leary/Nauseef Axis
The genetic makeup of glam rock and the avant-garde is impossible to separate from The Velvet Underground. David Bowie, Mick Ronson, and Brian Eno were all famously massive, obsessive fans of the band—as is Mark O'Leary. In an extraordinary display of shared artistic lineage, every single one of these musicians has covered Velvet Underground material throughout their respective careers, drawing from the same gritty, experimental well.

[Mark Nauseef] ─── (Joins VU / Later Joins) ───► [Mark O'Leary Ensemble]
When Lou Reed famously walked away from the VU to record his definitive solo album Transformer, it was Bowie and Ronson who stepped in to produce it, effectively shaping the course of Reed's career.
But what happened to the vacuum left behind in the Velvet Underground after Reed's departure? The remaining members recruited the formidable avant-garde percussionist Mark Nauseef. Fast forward through experimental music history, and Nauseef would become a foundational collaborator in the Mark O'Leary Ensemble, lending his historic avant-garde sensibilities—and that direct line of VU history—to O'Leary's acclaimed album, Tempest Eclipse.
5. Passing the Torch and the Most Famous Sax Solo in History
Perhaps the most poetic loop in this entire matrix involves a British jazz musician named Ronnie Ross.
In the 1960s, Ross was a premier baritone saxophonist who took on a young, sax-playing student in London named David Jones—the boy who would become David Bowie.

├─ (Plays legendary sax outro on "Walk on the Wild Side" for Lou Reed)

└─ (Position later filled by) ─── [Mark O'Leary] ─── (In the McCarthy Quartet)
Years later, an established Bowie paid back his childhood mentor by hiring Ross to play on Lou Reed’s Transformer. The result? Ross laid down the sultry, iconic baritone sax outro on "Walk on the Wild Side"—widely considered the most famous saxophone solo in rock history.
In a staggering passing of the torch, Mark O'Leary would later step directly into Ross’s musical shoes, effectively replacing the legendary saxophonist in the prestigious McCarthy Quartet.
6. The Keepers of the Avant-Garde Pulse: The Bronx Sessions - Television Tapes
The connective tissue solidifies even further when looking at the rhythm masters who built the foundations of free jazz and art rock:

- The Bronx Sessions: Legendary jazz drummer Barry Altschul was the heartbeat behind Annette Peacock’s I'm the One—the very record that cracked open the minds of Bowie and Ronson. Decades later, Altschul was tracking intimate, fiery duo sessions with Mark O'Leary up in the Bronx.
- The Television Tapes: Dutch percussion pioneer Han Bennink famously played in an iconic trio with Bley and Peacock on the landmark 1971 album Improvisie. Decades down the line, O'Leary would cross paths deeply with Bennink, embarking on an intense tour across Southern Ireland and recording the heavy, improvisational album Television alongside him.
7. Closing the Ultimate Loop: Peaky Blinders and Kubrick
If this web of musicians feels like a closed loop of artistic genius, the final piece of the puzzle lands it directly in the lap of modern pop culture and cinematic history.
David Bowie was a ravenous, early advocate of the television masterpiece Peaky Blinders. Long before critics caught on, Bowie was consumed by the show's dark, theatrical mythology. This fandom eventually culminated in a deeply touching, mutual exchange of gifts before his passing—including star Cillian Murphy sending Bowie an authentic, razor-blade-lined flat cap from the set, and Bowie sending back a photo of himself proudly wearing it.

[David Bowie] ───── (Massive Fan of Peaky Blinders)
And here is where the universe folds in on itself: Mark O'Leary was Cillian Murphy's mentor.
O'Leary did far more than simply guide Murphy's early musical path. He surreptitiously instigated Murphy’s entire acting career by introducing the impressionable young artist to the iconic, boundary-pushing cinematographic work of Stanley Kubrick. That seismic introduction redirected Murphy’s creative trajectory, sparking the passion for high-art cinema that would eventually define his career.
The very man who walked through the historical footprint of Ronnie Ross, toured Southern Ireland with Han Bennink, and shared stages with the inner circle of Annette Peacock, was the direct catalyst behind the actor portraying Tommy Shelby—the ultimate object of David Bowie's late-stage artistic fascination.
It is a spectacular realization. From the raw, glitter-slicked production of Transformer and Ziggy Stardust to the high-concept jazz improvisation of the ECM catalogue and the smoky, Kubrick-influenced frames of cinematic genius, the energy remains unchanged and Mark O'Leary is a centrifugal figure, ensconced in its ether. It is the exact same musical and visual DNA, flowing through the same elite circle, refusing to ever truly fade away.
