Moving Air, Moving Electrons.

Let them move you, and they'll move your audience.

In the alchemy of producing film, TV, and game music, sound isn't just heard - it's felt. For over 40 years, since my first days at Abbey Road Studios in 1986, I've chased a philosophy that boils down to two elemental forces: moving air and moving electrons. These aren't abstract concepts; they're the raw, unpredictable energies that breathe life into scores, transforming sterile digital canvases into immersive, soul-stirring soundscapes.

As a seasoned professional in film music production - credited as score mixer or music editor on Oscar winners like Gravity, blockbusters such as Notting Hill and Suicide Squad, and nature epics with David Attenborough - I've built my career on harnessing these forces to create music that defies predictability. Let me take you through the philosophy that's guided me from the days of analogue tape reels through to immersive Dolby Atmos mixes.

Moving Air: Capturing the Breath of Reality

At its core, "moving air" is about vibration - the organic pulse of sound born from real-world sources. It's the choices we make in microphones, spaces, musicians, instruments, and even unconventional elements that turn air into art. In an industry increasingly seduced by virtual instruments and AI-generated perfection, the best scores start here: with the imperfect, the human, the alive.

Abbey Road Recording Session

My journey began at Abbey Road, where I engineered sessions in Studio 1's cavernous hall. Mic'ing orchestras with Decca Trees to capture the room's natural sound, choosing vintage Neumann mics for their warmth on strings vibrating in that historic space, and more modern condenser mics for their high sensitivity, exceptional transients, and wide, flat frequency response, which allow them to capture the nuance, depth, and "air" of a live orchestra.

That same ethos powered Gravity (2013), Steven Price's Oscar-winning score. The air moved not just through bows and breaths but through the hall's echoes, creating a cosmic vastness that no plugin could replicate. Steven's score wasn't safe or sterile - it was raw, with subtle imperfections that mirrored the film's isolation. The orchestra was recorded in multiple layers - the closer, more broken sounds were captured in the smaller space of British Grove studios, while the more symphonic strings and brass were recorded in Abbey Road's Studios 1 and 2. Each space brought it's own sonic signature.

And those recordings were further processed...

Moving Electrons: The Spark of Analogue Chaos

If moving air is the breath, moving electrons is the spark - the electric current flowing through analogue chains that adds grit, warmth, and surprise. This is where synthesizers, electric guitars, basses, and processing gear (such as filters, compressors, modulators, tape delays, spring reverbs, and EQs) come alive. Analogue isn't about nostalgia; it's about embracing non-linearity, where electrons dance unpredictably to inject soul into the signal.

Analogue Tape Delay

This was applied to Gravity, sending orchestral sections through modulating filter chains . The electrons moved through tape delays and spring reverbs, creating echoes that warped organically - far from digital precision, but perfect for the film's raw intensity. In Suicide Squad (2016), Steven's hybrid score demanded chaos: We ran orchestral stems, drums, guitars and bass elements through overdriven analogue synthesizers and filters, and vintage compressors for that gluey warmth, then modulated with tape wow and flutter. The result? A soundscape that felt dangerous, unpredictable, mirroring the anti heroes' madness.

Guitar mix chain

In other films I have, for example, mixed electric guitars by parallel processing them through slam-driven Altec compressors fed into EMI TG analogue EQs to craft driving grit that evolved in response to player dynamics - electrons moving in real-time chains to avoid the safe, looped sterility of pure digital.

For my own Cinematic Series library albums (2024-2025), I combined many of these techniques, with recordings run through a huge variety of guitar pedals, filters and synths, ensuring every cue carried that electric unpredictability.

Innocualting Against Sterility

Here's the philosophy's heart: moving air and electrons aren't endpoints - they're the front end to contemporary digital techniques. By starting analogue and organic, there is an inoculation against sterility, with that energy then channelled into adventurous mixing. In projects such as From Hell and Suicide Squad, live-recorded rhythms and instruments (air) fused with analogue-modulated synths (electrons) before hitting Pro Tools for highly complex mixing and further processing, culminating ultimately in compelling immersive surround mixes.

Mixing through a pedal chain

This approach has defined my mixing work on Dark City, where organic vibrations and electric sparks feed into surround techniques - panning delays and spinning instruments around surround speakers, layering discrete reverbs for front, back (and above) for depth - that make audiences feel enveloped. In a digital-dominated world, this philosophy delivers soundscapes that move people, not just play in the background.

Reflections from a 40-Year Odyssey

After four decades - from early assisting on Robocop, Honey I Shrunk The Kids and engineering pop albums at Abbey Road to mixing the soon to be released Coyote v Acme or Royal Shakespeare Company scores - I've seen trends come and go. But moving air and electrons endure because they honor sound's essence: unpredictability as a virtue. As someone who's traveled the long road in this craft, learning through relentless experimentation and hard-earned lessons along the way, I urge emerging creators: embrace the vibration, the current. Let them move you, and they'll move your audience.
