There's a good documentary on Hatsune Miku here - it's in Japanese but with English subtitles (click the 'CC' logo in the bottom right of the YouTube player to turn them on): http://www.youtube.com/watch?v=xBZOlipfjkQ

I find the Hatsune Miku phenomenon somewhat amusing at the moment, given the trend of overt Autotuning in pop music - while virtual singers' voices are getting more realistic, real singers' voices are being manipulated to sound impossibly accurate and digital.

It's also an interesting study in image and marketing: Crypton really pushed the concept of associating a character with the voice, as if Vocaloids were virtual pop stars whose services you could buy, rather than just another virtual instrument.

I guess its the next logical step. If the pop singer doesn't write their own song, doesn't sing their own song live, and doesn't understand the lyrics; you might as well just use a hologram.

I never realized how frightening a life sized version of an anime character is. Still, its an interesting phenomenon.

Life imitates anime - anyone else get a Macross Plus flashback about the concept?
Now someone just has to hack it during a live performance.
Indeed. That was the first thing I though: Macross!

It did not end very well. The movie/series explored a dark side of this tech.

+1 Sharon Apple Flashback!

The Macross Plus soundtrack was one of my all time favorites from the ridiculously talented Yoko Kanno.

Now to wait for Veritech's to be invented...

Wow! This reminds me of the book Idoru by Willam Gibson.

Idoru on Wikipedia: "In the post Tokyo/San Francisco earthquake world of the early 21st century, Colin Laney is referred to agents of the aging mega-rock star Rez (of the musical group Lo/Rez, and seemingly very much styled after former The Smiths frontman, Morrissey) for a job using his peculiar talent of sifting through vast amounts of mundane data to find "nodal points" of particular relevance. Rez has claimed to want to marry a synthetic personality named Rei Toei, the Idoru (Japanese Idol) of the title, which is apparently impossible and therefore questioned by his loyal staff, particularly by his head of security, Blackwell.[...]" source: http://en.wikipedia.org/wiki/Idoru

I'm starting to think Gibson is writing the future.
These days, he focuses on writing the present
But only because by his point of view, the present is effectively the future he looked forward to. I've always felt it's both an interesting and bold position for a writer of sci-fi to take.
Does this mean that sometime soon, Gibson will be writing historical fiction?
In one sense, he already has.

this is my favorite line in idoru, which I think is relevant to hn (realizing now that even the name of the collective is prescient):

"Someone had the idea to turn the killfile inside out. This is not really how it happened, you understand, but this is how the story is told: Hak Nam were angry, because the net was very free, you could do what you wanted, but then the governments and the companies, they had different ideas of what you could and couldn't do. So these people, they found a way to unravel something. A little piece, a piece, like cloth. They made something like a killfile of everything, everything they didn't like, and they turned that inside out."

This reminds me of a short cyberpunk story. I can't remember the name/author, but it was about a world where the next level of entertainment was essentially generated from a brainmap of the "artist." There was a girl who was disabled/disfigured/diseased, and she ended up becoming the biggest and most popular artist ever due to the raw emotions she was conveying.

At the end she transfers her consciousness "to the cloud" and becomes completely digitized.

Anyone else read this?

This sounds like a really interesting story. Thanks for the tip.
This looks more like rear-projection video (note the starburst in the back of the stage) or Pepper's Ghost, although the scrim is too vertically oriented to be that.

Nothing here looks 3D, but of course these videos are very carefully shot and enhanced from all appearances.

And all the videos are from near-straight-on. Because this type of projection (onto a flat, semitransparent screen) gets skewed when at an angle.
You're right, this is the same technology used for the Gorillaz tour a few years back. In that case, some very talented, real musicians were hiding their wrinkles and gray hair behind the screens.
Is this really that different from Gorillaz? They are also cartoon personas that perform music.

If it gets to the point where an artificial intelligence composes and performs, then we will be in Gibson's Sprawl.

Slightly different. Gorillaz band members are usually voiced by one real artist (although this artist can change from album to album), whereas Hatsune Miku is one step removed - while there was a real voice actress providing the foundation for her voice, the actual lyrics sung don't pass through any human mouth.

The persona of Hatsune Miku also seems to have evolved a little more organically: the style and personalities of Gorillaz are basically driven by Damon Albarn and Jamie Hewlett; Hatsune Miku started out as an image on a software box, but got adopted by the internet community who produce videos based on her, with quite diverse personality and style.

As for artificial intelligence composition, Emily Howell is probably the closest we've got at the moment: http://arstechnica.com/science/news/2009/09/virtual-composer...

So do they record and then playback, or is it voiced fully by computers?
Fully voiced by the computer. Think of a midi keyboard that also has a 'syllable' component for each note: So for example you make her sing the syllable 'Ka' in middle C. There are also a dozen or so other knobs that control how it is sung at that particular point in time.
So the singing is synthesized, but the band is real?

Backwards world :)

Entirely computers. Hatsune Miku and similar software are basically voice synthesizers geared towards music, as I understand it, not hugely unlike other text-to-speech programs but with more control of pitch, tone, and so forth.

Also, as far as making artificial intelligences compose and perform, it might be interesting to hook up Hatsune Miku to a Markov chain generator[1], and feed it a bunch of j-pop as input. Would probably take some fine-tuning and modification to get it to give output that the synthesizer would understand (as it would be dealing with both words and notes), but it's not too far fetched.

[1] Which isn't an AI by any means, being more of way of generating text based on statistical correlations between words in the input body of data, but it comes up with some rather interesting things.

You input the lyrics, notes, scale, tempo and dynamics; the software will produce a voice based on those parameters. Then you can record it to share it as an audio file. Here's a quick FAQ on the official site: http://www.vocaloid.com/en/technical_faq.html

I want to see the crossover!

EDIT: Really, I want to see her animated with the keyframes by Hewlett.

We can make computer controlled, real-time holographic displays now? That seems like bigger news than a rockstar.

Isn't that the holy grail of 3D displays?

It's still just a projection onto some sort of medium.
If we are talking a "virtual" rock star, I prefer a hybrid approach, like sushi k in snowcrash. A real, single musician writing and performing, but using different mediums - the metaverse in snowcrash, or maybe even holograms in real life.
Hmm, interesting. Can't wait for the first time they have to sue a real flesh and blood human being over the copyrights to a song by a hologram.

Still, the future its going to be awesome.

I would guess that with most pop. music performers the copyright to their songs are owned by the "Record Label" or company that signs their paycheck.

None of the money from current RIAA lawsuits goes back to the artists.

Wow! Japan never ceases to amaze me.

Would be interesting if the 3d hologram can be controlled by a human in real time.

Although that would probably suck for the self-esteem "I'm not good enough, they put a fake anime hologram in my place".

Reminds me of Genki Rockets, which also has a "vocaloid" singer synthesized from a couple of female singers. I first found out about this sort of think when I was working for Henk Rogers (Tetris mogul) down in Honolulu. The office was always full of really big names from Japan, like the guys from Square Enix, Nintendo, etc... The guys that made Lumines II were in the office playing some sick blu-ray footage of a Genki Rockets concert and from that moment on I was hooked. The DJ was wearing an astronaut suit and there was a hologram projection of Lumi singing and dancing above the crowd. So sick!

Here is a link to Genki Rockets -- http://en.wikipedia.org/wiki/Genki_Rockets

I wasn't expecting an anime character, but more something like in the movie S1m0ne (http://www.imdb.com/title/tt0258153/).

In that movie, the movie/pop star is computer generated but is a "real" person and there actually is a scene with a 3D hologram of her on stage.

As someone else mentioned, though I find that to be fascinating, I'm more interested in what they mean exactly by "3D hologram" and how it works.

An unrelated observation, is the layout of this site completely ripped off of techcrunch?
'Rock'-star? That's not rock.
I guess The Archies were ahead of their time.
I have to admit, I'm getting a little uncanny-valley vibe from that. The movement is too crisp (they've got to be digitizing the movement of a human dancer?) in combination with the cartoony appearance.
Yes. I think it would've actually worked better if the toon shading was a bit more "toony" and the frame rate was lowered to 12. It would seem more "magical" that way, like the mixed live/cartoon scenes in Mary Poppins.
The otaku subculture is getting creepier.
By holding pop concerts? Have you seen anything else they do?
This isn't really limited to otaku subculture at all. There will be lots of different people who enjoy this.
This disturbs me beyond words.

It seems like a real loss for humanity and a real gain for special interests (although it can be argued that humans can be manipulated as easily as this hologram for such purposes).

In any case, this isn't part of any future I'll be embracing.

So a 'performer' that doesn't write their own songs, sing their own songs or even do their own choreography isn't already a real loss for humanity?

We elevate talentless, brainless schmucks to the pinnacle of our culture apparently just to watch them fall from grace. How is going one step further to an artificial performer less human? At least no one is hurt when they go on a crack/booze/heroin/etc binge. And at least I won't have to hear of some dumb bitch shaving her head and nigh-on abusing her kids on a daily basis.

This disturbs me beyond words.

Popular music hasn't been doing too well on the all-important "making grown-ups uncomfortable" front recently. Great to see it catching up a bit.

I didn't know it was possible to have video 3d holograms like that! Does anyone know where to find out more about the technology used?
If only the crowds could also be an hologram.
