It was a technological feat that made history, wowed audiences and brought a dead rapper back to life. In April 2012 at the Coachella festival in California, Tupac Shakur took to the stage with Snoop Dogg and Dr Dre. He’d been dead for 16 years, killed in a drive-by shooting in Las Vegas.
But this was Tupac the hologram, foul-mouthed and lifelike, performing before a “shocked and then amazed” crowd.
Since humans first delighted in the sound of music, advancements in technology have made musical expression immortal. Throughout history, innovators have strived to create original, accessible and eternal performances.
As engineering knowledge developed, musical instrument design advanced. Many classical composers introduced pioneering instrumentations into their scores, adding depth and color that broadened the listening experience.
Accurate systems for matured notation, offering music an essence of immortality through printed manuscript. In 1853 Edouard-Leon Scott de Martinville’s phonautograph pioneered an audio recording technique.
In 1912 WC Handy composed “Memphis Blues”, a song that took the US by storm and influenced the development of popular music. Published on paper, it was wildly popular in the dance halls and soon every band in America was asked to play it. This public demand was recognized by an fledgling recording industry, which soon flourished.
Technology = creativity
A breakthrough in the quality of music captured came with the advent of hi-fi and stereo introduced by Yamaha. Those who artistically embraced the technology could transport a lifelike performance experience into the homes of the masses. One of the biggest bands of the 1970s and 1980s, Swedish group Abba, embraced this technology pioneering recording techniques, which is still used as the standard today.
Behind this technology was the creative genius that produced millions of record sales and performances dominating the 1970s and beyond. After the demise of the group, Benny and Björn expanded into the theatrical genre, composing musicals. Along with their interest in emerging technology, this sowed the seeds to recapture and reinvent the Abba machine 40 years later.
May 2022 sees the latest technological advances in musical immortality when Abba return to the live stage after a 40-year absence. But this time they return as humanoids – the digital holgram “twins” of the original global phenomenon.

George Lucas’s Industrial Light and Magic has created holographic lookalikes that interact with a live band in a specially designed purpose-built theater in east London. Benny, Björn, Frida and Agnetha have provided the pre-recorded vocals and motion-captured movement, which will then be reproduced by the digital avatars.
The dopplegangers are more youthful in their appearance – around their 30s, when they were at the peak of their fame – raising an interesting conundrum concerning Abba’s human mortality against their new immortality in the metaverse.
Abba’s music is undoubtedly timeless; the simple tunes with incredibly complicated structures appeal to millions. The “Abbatars” are a reinvention for a new audience, but will they continue beyond the lives of their originals, with new creators pulling the strings?
Besides Abba and Tupac, there are other instances where “digital twinning” has been identified as a key money-making strategy. The digital band Gorillaz’ 2006 Grammy performance blended flawlessly with Madonna’s. And Richard Burton’s hologram performed on a global tour of War of the Worlds in another 2006 performance.
Music in the metaverse
Customizing 3D avatars has become a way for artists to create virtual brands across several digital platforms. They can connect virtually with fans and increase loyalty and engagement, while fans can interact, express themselves and experience new things.
This is now achievable using AI software to make holograms, as researchers at the Massachusetts Institute of Technology (MIT) demonstrated in an experiment that created holograms almost instantaneously.
Ziva Dynamics, a pioneer in simulation and real-time character creation, employs synthetic AI-powered avatars to create autonomous and complex movement simulations based on real muscle, fat, soft tissue and skin contact.
In April 2021, in a project called Lost Tapes of the 27 Club, Google’s Magenta AI was even used to compose songs in the styles of musicians who notoriously died at the age of 27, including Jimi Hendrix, Jim Morrison and Amy Winehouse.
These technologies have the potential to create realistic synthetic and AI holographic representations of departed artists, allowing them to continue creating, influencing and performing for future audiences.
Epic Games, creators of the phenomenally successful Fortnite, predicts that digital twins will combine with the metaverse, an emerging network of fully immersive digital worlds.
Disrupting the music business
Whereas live tours are time-intensive and costly for new artists, a low-cost metaverse “tour” might be a new way for music lovers to see live performances. Virtual performances by Justin Bieber, DeadMau5 and The Weeknd have already become popular recently.
In this emerging branch of the music industry, record labels and marketing firms could be replaced by decentralized autonomous organizations (DAOs). DAOs are online organizations that operate like cooperatives, making all decisions jointly.
DAOs are already disrupting the music business – along with NFTs (non-fungible tokens), which are a way of transferring property between people online. In October 2021, PleasrDAO – a collective of decentralized finance (DeFi) leaders, early NFT collectors and digital artists – paid $4m (£3m) for Once Upon a Time in Shaolin, an album by New York hip-hop legends Wu-Tang Clan.
While the release of the album predates the rise of NFTs, PleasrDAO now owns the rights and has imposed strict restrictions on duplication, distribution or public exhibition. A music-focused DAO like Pleasr may acquire bulk concert tickets, finance and organize events and manage fan-owned record labels and marketing agencies to secure investable commodities like first-edition LPs, artwork and instruments. This has the potential to benefit fans, new music genres and artists alike.
This creates a new, decentralized route to the market for artists free of corporate interests or interests of individual producers, developing a fairer landscape for the future. With digital avatars likely to be at the center of this new vanguard, it will be fascinating to see how it develops in the months and years to come – and whether it will be enough for music audiences.
