If you missed Miku on stage in Los Angeles then you may want to catch her at the Anime Festival Asia 2011! And yes - it will be a similar setup to the Los Angeles gig in 3D.
Stolen from the official site below.
Hatsune Miku is a computer music software that enables users to create synthesized vocals of unprecedented quality and remarkable realism by just typing in lyrics and melody, using voice samples of seiyuu Saki Fujita. Powered by Yamaha's Vocaloid (Vocal + Android) technology, Hatsune Miku was developed by Crypton Future Media in Sapporo, and released on August 31st, 2007.
Since then, there have been more than 30,000 songs and movies about Hatsune Miku posted in a popular Video sharing web site such as YouTube and Nico-Nico- Douga(Japan). In 2008, Hatsune Miku performed for the first time on stage at Animelo Summer Live 2009 in front of a crowd of more than 25,000 people.
This simple software, with a cute voice and an illustration of its avatar on the cover, created not only large amounts of CGM (consumer generated media) music but remarkable numbers of derivative illustrations and dedicated free software as well.
Anime Festival Asia will premiere the first Hatsune Miku concert in Asia. The concert will be a sequel to the most recent live production in Sapporo, which pushed the live Miku experience to a whole new level.
Also forgot to mention but Danceloid and myself are to be part of the bonus material that comes with the Blu-ray of the Los Angeles concert ^^;
I didn't have time to check whether my flies were undone or not so I left it to Fukuoka-san to check for me ^^;
