First there were the ABBA-tars bashing out their hits in a purpose-built East London arena, now we hear that an Elvis hologram will perform in the capital later this year.
In between there is this rather more Zen-like virtual performance by the Japanese composer Ryuichi Sakamoto, who died last March.
Unlike ABBA Voyage, the 45 minute concert involves donning headgear and a neckstrap contraption, but allows you to circulate 360 around the performance, and get 'up close' to the 3D Sakamoto, bent intently over his Yamaha grand.
The visuals are certainly fuzzier than the Swedish popstars, but if the silver-haired composer looks spectrally unreal, the sound is perfectly crisp, and the impression of Sakamoto brilliantly playing his stirring music for our small audience is the best thing about this.
The optically transparent goggles mean that you see right through your fellow concert-goers, and have to peer above or below them to make sure you don't bump into each other.
'Dimensional art' effects of stars, puffy clouds, falling leaves and twisting roots enhance the Augmented Reality, but in the end it's the swelling notes, the hauntingly beautiful music, and the intensity of the performance that count.
Tracks includes what he describes as his surprise 90s hit Energy Flow, and music from his Oscar-winning soundtrack to The Last Emperor, and Merry Christmas Mr. Lawrence, which he also starred in alongside David Bowie and Tom Conti, and which brought with it gusts of 80s nostalgia.
The concert ends with his mournful elegy for The Last Emperor director Bernardo Bertolucci, an apt close to a contemplative and gently uplifting rather than earth-shaking evening.
Sakamoto was working on Kagami with Tin Drum at the time he was diagnosed with terminal cancer, and as a cutting edge electro-pop pioneer, he clearly embraced this new technology.
Would I prefer to have experienced it live? Absolutely, but in the absence of these past great performers, this is the next great thing. It's just that now the VR genie is out of the bottle there is no going back.
Kagami runs at The Roundhouse in Chalk Farm until January 21.
