Understanding the Layout of a Large Stadium Concert

A Field Observation of the Major Structures Behind a Modern Stadium Show

When most people enter a stadium concert, their attention immediately goes to the performers, the music and the spectacular lighting effects. Few people notice the temporary engineering systems that make the show possible.

In reality, a modern stadium concert is far more than a stage. It is a temporary production site made up of multiple independent but interconnected structures. Each system has its own purpose, from supporting performers and equipment to managing sound, lighting, audience experience and backstage logistics. Understanding how these systems work together is essential when planning a complete Concert & Event Stage Solution.

During the construction of the 2026 Guangzhou Pearl Beer Festival Music Festival, we observed the installation process and documented the major structures before the audience entered the venue. This article introduces the overall layout of the site and explains the role of each major area. More detailed engineering discussions will be covered in separate articles throughout this series.

1. Main Stage — The Centre of the Production

The main stage is naturally the visual focus of the entire concert, but it is also the most complex temporary structure on site.

In this project, the stage consisted of several integrated components rather than a single platform.

The primary performance area was covered by a large Roof Truss System supporting lighting, video equipment and other overhead production loads. Beneath the roof, three arched lighting trusses created depth behind the performers while framing the central LED wall.

Unlike many standard concert stages, this project also incorporated large Ringlock Structures on both sides of the main stage. These side structures supported the side LED screens while also concealing backstage working areas beneath them.

Extending from the centre of the stage was a long walkway leading toward the audience. At its end, a circular performance stage created a secondary performance area that allowed artists to interact with spectators located farther away from the main stage.

Two staircases connected the main stage to the walkway, allowing performers to move efficiently between different performance zones.

Behind the side Ringlock structures, temporary entrance tents connected directly with larger changing-room tents. This arrangement allowed performers and crew members to reach the stage while remaining hidden from the audience.

Although these components appear to form one stage, each performs a different production function and together create a complete Stage System. Each component will be discussed individually in later articles.

2. Front of House (FOH)

Located near the centre of the audience area, the Front of House served as the technical control centre of the concert.

Unlike many conventional FOH structures, this project used a hybrid arrangement consisting of a ground-level control tent together with a tall Ringlock production tower.

The structure also incorporated multiple LED displays, elevated working platforms and several weather-protected technical areas.

The design demonstrates how sound control, lighting operation and production management are integrated into a modern live event. We discussed this engineering approach in detail in Why Is the FOH Positioned in the Middle of the Audience Area?

3. Relay Towers

Several tall relay towers were positioned farther back within the audience area.

These black steel structures stood approximately 20 metres high and immediately attracted attention because of their unusual foundations.

Each tower was supported by a heavy steel base surrounded by four large water tanks. At the top of the tower, guy wires extended downward and were secured to the water tanks, creating additional stability for the temporary structure.

Although they appear relatively simple from a distance, relay towers perform important production functions within a complete Stage Sound System, particularly when sound must cover very large audience areas.

Their engineering design, stability and operational role will be discussed in a dedicated article later in this series.

4. Audience Area

The audience area consisted of two different seating systems.

The permanent grandstands of the stadium surrounded the performance area and provided elevated viewing positions.

On the stadium floor, however, a temporary seating system had been installed to create a dedicated VIP area closer to the stage.

This combination allowed organisers to accommodate different audience experiences while making full use of the stadium's existing infrastructure.

From an engineering perspective, audience planning is not only about capacity. It also influences evacuation routes, viewing angles, sound coverage and the placement of temporary structures throughout the venue. These considerations are equally important when designing a complete Event Stage System.

5. Delay Speaker Platforms

Behind the FOH, at least two delay speaker platforms could be observed.

Unlike the much taller relay towers, these delay systems were installed on relatively low Ringlock platforms approximately two metres above ground level.

Their position behind the FOH allowed them to cover audience areas farther away from the main stage while remaining aligned with the overall Line Array Speaker System.

Although visually modest, delay speaker platforms are an essential component of large-scale concert audio design.

Their placement, height and relationship with the main line-array system will be examined in a separate article.

6. Backstage Areas

One area that remains almost invisible to spectators is the backstage support zone.

Behind both sides of the stage, large temporary tents provided changing rooms and working spaces for performers and production staff.

Smaller entrance tents connected these backstage facilities directly to the stage, allowing performers to enter and exit without crossing public areas.

Because these facilities were partially hidden beneath the Ringlock side structures, they remained largely invisible to the audience while providing efficient circulation routes behind the scenes.

This illustrates an important principle of temporary event engineering: many of the most critical operational spaces are intentionally designed not to be seen. Efficient backstage planning is just as important as the visible Stage Platform itself.

Understanding the Site Before Understanding the Engineering

A large stadium concert is often described by its performers or stage design, but the temporary engineering behind the show is equally remarkable.

The roof stage supports the performance.

The Ringlock side structures integrate LED screens and backstage access.

The FOH coordinates technical operations.

Relay towers extend sound coverage.

Delay speaker platforms maintain audio consistency.

Backstage tents support performers and crew.

Temporary seating reshapes the audience experience.

Each structure has its own purpose, yet none operates independently. Together they form a temporary production environment capable of transforming an empty stadium into a fully functioning concert venue.

Understanding this overall layout makes it much easier to appreciate the engineering decisions behind every individual structure. Throughout this series, we will continue exploring these systems one by one, while connecting them to the broader knowledge found in our Concert & Event Stage Solution and Stage Sound resources.
