London’s New Year’s Eve Fireworks remains one of the UK’s most prominent annual live events, combining public spectacle with global broadcast reach. For the 2025/26 edition, music direction once again played a central role in shaping the experience, with ON THE SLY returning as music directors and soundtrack producers.
Music As Structural Framework
Commissioned by the Greater London Authority and broadcast live on BBC One, the twelve-minute display is carefully constructed around its soundtrack. Rather than acting as accompaniment, music provides the structural backbone of the show.
Once the overarching creative direction is defined, the soundtrack establishes timing, pacing and emotional progression. Pyrotechnics, lighting and visual cues are then choreographed to align precisely with the music. This reinforces the role of sound as an organising system within complex, multi-layered live events.
Creative Collaboration At Scale
For the 2025/26 celebrations, ON THE SLY worked alongside lead creative agency Identity and co–music director Kojo Samuel. This collaboration required close alignment across creative intent, technical constraints and broadcast requirements.
The fireworks take place across a wide urban footprint, with multiple firing locations, lighting elements and sightlines along the Thames. Music direction, therefore, needs to account for both on-site audiences and millions watching remotely. The soundtrack must read clearly across different listening contexts while maintaining narrative cohesion.
Reflecting Theme And Place Through Sound
This year’s creative theme focused on connection and unity. The music soundtrack was developed to support that idea by drawing on a broad range of artists and genres that reflect London’s cultural breadth.
For B2B audiences, the key point is not the specific track choices but the process behind them. Music selection was used to define tone shifts, signal transitions and support moments of collective emphasis. In events of this scale, subtle changes in tempo or instrumentation can influence how audiences perceive time, anticipation and release.
Synchronisation Across Disciplines
Delivering a tightly synchronised show requires detailed coordination between music, fireworks programming, lighting design and broadcast direction. Every cue is locked to the soundtrack, meaning that changes to music ripple through multiple production systems.
ON THE SLY’s role involved working across departments to ensure that the soundtrack remained the reference point for delivery. This approach reduces ambiguity during live execution and supports consistency across rehearsals, technical runs and the live broadcast itself.
For producers and technical directors, the project illustrates the importance of assigning clear ownership of core creative elements within large delivery teams.
Broadcast And Public Realm Considerations
Unlike ticketed events in enclosed venues, London’s New Year’s Eve Fireworks operates simultaneously as a public realm experience and a televised programme. Music direction must therefore function across both domains.
The soundtrack needs sufficient clarity and narrative drive for broadcast audiences while remaining effective in outdoor conditions where sound dispersion and environmental noise vary. Balancing these demands is a specialist discipline that sits at the intersection of live events and television production.
Implications For Experience Professionals
London’s New Year’s Eve Fireworks provides a strong case study in how music direction supports large-scale civic events. It demonstrates that sound is not a secondary layer but a primary tool for structuring experience, aligning teams and communicating meaning at scale.
The project highlights the value of integrating music early in the creative process. For commissioners, it shows how clear creative leadership around sound can improve delivery confidence across complex partnerships.
As cities continue to invest in high-profile moments that operate across physical and broadcast space, the role of music direction is likely to become even more central. The 2025/26 fireworks underline how disciplined, collaborative soundtrack production can help a city speak with a single, shared voice at a defining moment.
