15New toys: drones, spatial audio, wristbands and holograms

The short version: Since about 2015 the spectacle has picked up four new tools. Drone swarms draw pictures in the sky, at a scale that has grown from a few hundred aircraft to more than ten thousand, under aviation rules that most stage crews have never had to read. Spatial audio systems place sounds around a room instead of firing everything from two stacks. LED wristbands turn the audience into a lighting fixture. And real-time engines let giant video surfaces react to an unscripted set. Meanwhile, the "hologram" remains what it has been since the Victorians: a reflection on a sheet of glass or film.

Drone shows

The modern drone show started small and pre-recorded. Intel's 300 Shooting Star drones in Lady Gaga's Super Bowl halftime show on 5 February 2017 were filmed days earlier, because the flight restriction around the Houston stadium covered more than 30 miles and allowed no exemption for the show³⁶⁴. Each drone reportedly weighed about an ounce and flew for about 20 minutes³⁶⁴.

Within eight years, the numbers went up by a factor of fifty. Treat every figure below as a dated snapshot, because records in this field fall within months, and several have ragged edges:

• Vietnam, 28 April 2025. 10,518 drones from the Chinese supplier DAMODA, recognized by Guinness as the largest drone light show by number flying simultaneously. The record flight appears to have been a rehearsal, and later public shows were canceled amid unconfirmed speculation about collisions³⁶⁵.
• July 2025. Guinness reported an 11,000-drone show creating a record-breaking image³⁶⁶.
• Liuyang, China, October 2025. About 16,000 drones launched from a single computer, reported as 15,947 by one outlet and 15,974 by another; we did not see the Guinness listing itself, so the exact count is unconfirmed³⁶⁷³⁶⁸.
• Manvel, Texas, March-April 2026. Aerial Illuminations and UVify set five Guinness records in a run of public shows leading up to Easter that followed church programs, monitored by a Guinness adjudicator on site, including the largest flying LED screen formed by drones (9,969) and the most drones launched in a week (66,123). The crew was 100 people and the equipment was valued at about $25 million³⁶⁹.

The rules are the part a production manager needs, and they are national; what follows is as of October 2026. In the US, a drone show runs under waivers to the FAA's Part 107 small-drone rules: chiefly §107.35, which normally limits one remote pilot to one aircraft, plus §107.39 for flights over people, where the FAA counts concerts and festivals as open-air assemblies and treats sustained flight over a crowd differently from brief transit³⁷⁰. Night flying and visual line of sight have their own waivable rules, the FAA aims to decide within 90 days, and applicants have to set out risks and mitigations³⁷⁰. In the UK, swarms, flights close to crowds and flights above 120 meters need a Civil Aviation Authority operational authorization in the "Specific" category, assessed since 23 April 2025 under the UK SORA method³⁷¹. EU countries use the same European framework the UK inherited, so a show there typically needs a national Specific-category authorization too (our inference; we did not read the EASA rules directly).

The practical constraints at a festival, in our summary, are airspace, crowd overflight, wind and reliability. DAMODA claims a 99.999% reliability rate³⁶⁵; taken at face value, and read as a per-drone, per-show rate, across 10,000 drones that is still about one failure in every ten shows. Whatever happened in Vietnam (the cause is unconfirmed), the failure that matters over a crowd is an aircraft falling.

Spatial audio

A conventional PA sends a left and right mix (or one mono mix) from the sides of the stage. Object-based audio instead treats each sound as an object with a position, and the system works out which speakers should play it. Beamforming shapes where the sound goes, so that different parts of a room can hear different levels or even different content.

The best-documented club attempt was Dolby Atmos at Ministry of Sound in London in 2016. The Box got 16 Martin Audio ceiling speakers, for more than 60 speakers on 22 channels³⁷² (the club's Wikipedia page says 64 speakers³⁷³). The method shows why it did not spread. Producers split tracks into stems, kept bass and drums in the stereo bed, and turned pads, vocals, effects and drops into objects pre-panned in Pro Tools; those then played through a proprietary Dolby DJ app mapped to CDJ-2000s and a DJM-900, and could be moved live³⁷²³⁷⁴. It needed specially prepared tracks, one app, and that one room. Dolby called it "just the first stage"³⁷².

L-Acoustics' L-ISA system has also gone into a club: Mercury Space, on the 40th floor of a Moscow tower, which the company bills as "the first nightclub installation in the world" for L-ISA, with a frontal array, eight surround speakers and ten delays³⁷⁵. That is a vendor case study without a date.

At the top end, the audio is part of the building. Sphere in Las Vegas uses a HOLOPLOT system of 167,000 individually amplified drivers behind its interior LED screen, with claimed 3D beamforming that keeps level consistent over distance and can send different content to different sections, plus haptic seats³⁷⁶. Those claims come from a press release, with no published frequency, level or measurement data³⁷⁶. Systems like this are capital projects for one venue, not touring gear (our observation), and that is the real limit on spatial audio at electronic dance music shows: the tracks are mixed in stereo, and most rooms are rented for one night.

Crowd wristbands

LED wristbands make every audience member a pixel. The two main types differ in how they hear the lighting desk:

• Infrared. PixMob's bands use an infrared receiver like a TV remote's, and only light while they keep receiving a repeated code, so a band that misses the signal stays dark. A teardown found seven RGB LEDs, two AAA cells and about 0.6 watts at full white, good for six or seven hours³⁷⁷.
• Radio. Xylobands uses radio transmitters that send color, timing and sequence data; the company says one transmitter can cover an arena, and a DMX-to-radio interface lets a lighting console treat the crowd as a fixture, with zones mapped across the audience³⁷⁸. It says it pioneered radio-controlled bands on Coldplay's Mylo Xyloto tour³⁷⁸.

Wristbands are also a waste stream. PixMob says its bands come back for reprocessing at an 86% average return rate, a company figure relayed by the independent teardown, which also notes that the strap may be plant-based but the electronics and batteries are not³⁷⁷.

Real-time engines and "AI"

The other big shift is from pre-rendered video to content generated live. When Moment Factory built Phish's 2024 Sphere shows, the team said pre-rendering at Sphere's resolution was impractical because of data size and render time, and the visuals had to follow improvised jams; so Unreal Engine generated them in real time, with ten parameters such as speed, color and bloom run from a lighting console³⁷⁹. That is a vendor case study from a jam band, but the logic carries straight over to DJs (our inference): a real-time engine lets the visuals follow a set that nobody wrote down in advance. Anyma's "The End of Genesys" at Sphere added robotic arms playing cellos on its side towers and motion seating on the drops; the review does not say how its visuals were made³⁸⁰.

"AI" is the label of the moment, and it mostly means music analysis. The SoundSwitch integration in rekordbox, released in September 2026, analyzes a library for phrases and instrumentation and auto-generates a light show per track - and its announcement does not call that AI¹⁴⁵. MaestroDMX, a box marketed in 2022 as an "AI-powered lighting designer", listens for intros, builds, drops and silence and drives DMX in real time; the reviewer called "AI" "a vague term" and could not test it³⁸¹. Our reading: beat, phrase and section detection mapped to pre-designed looks is real and useful, and calling it a lighting designer overstates it.

Holograms, honestly

The "Tupac hologram" at Coachella in 2012, and nearly every concert "hologram" since, is Pepper's ghost: a bright hidden image reflected off a semi-transparent angled film (Victorian theaters used glass) so that it appears to stand on stage³⁸². The image is flat. As the show-control writer John Huntington put it, walk to the side and "you would NOT see the side of Tupac's head", so it fails the defining test of a hologram - parallax that changes with your viewpoint³⁸². Real holography records the light field of an object; nobody, Huntington wrote in 2012, has yet created "a viable, large scale" volumetric display³⁸².

Regulators have tolerated the word. In 2012 the UK Advertising Standards Authority did not uphold a complaint against Musion's "3D Holographic Projection" advertising: it accepted that the effect "was not genuinely three-dimensional and did not use holography", but ruled that audiences would not read the claim literally³⁸³. So "hologram" is tolerated marketing language for a 2D illusion, at least in the UK under that 2012 ruling. For the crew, the production facts follow from the optics (our summary): a Pepper's ghost needs a large tensioned foil, a very bright projector or LED source, a dark stage, and an audience kept within the viewing angle, because from the side the trick disappears.
