That will just sound like lip syncing unless the cover band undergoes some heavy cosmetic surgery. The fun of a cover band is watching a rendition of a song where the band are being themselves.

For a cover band sure, but a "tribute show" I associate more with trying to exactly match an experience no longer available (the tribute-ees are dead or aged out in some way).

People aren't going to the Van Halen Tribute Show because they're really excited to see John Smith's creative reinterpretation of Eddie's guitar solos.

Why not skip the cosmetic surgery and just use a projected, AI mapped face swapper? I do think you would still hear the variation from the live performer, e.g. their rhythm, their breath, their vocal fluctuations, simply with the AI voice changer software slapped on top of it.

I’m not sure how fun the concert would be – you’re right about that – but tech like this is definitely has the potential to transform many facets of the entertainment industry.

The Tupac hologram was not a good idea
