Hatsune Miku is a big star in Japan who sells lots of records but who is mostly famous for her live shows. Which is more impressive than you might initially think because she's a fucking hologram. Singularity Hub says...
Hatsune Miku is a rising star in Japan and abroad, singing catchy J-pop that matches her blue-green hair. She's also a virtual avatar created by Crypton Media using Yamaha's Vocaloid voice synthesizer. That hasn't stopped her from amassing a legion of fans who really love her work. I mean really love it. Check out the crowd frantically waving glow-sticks and singing along with Hatsune Miku as she appears via a ‘3D hologram' on stage in the videos.
Go here and here and here to watch this in 1080i, and you should to see how insanely clear this is. Thank god the Japanese spend most of their time inventing new ways to slaughter every living thing in the ocean and fuck stuff (which I think we both know is how Hatsune came about). If those perverts put their mind to conquering the world, I wouldn't even have time to finish this sentence in English.
