As an encore to his keynote at the GameCity Squared festival last Friday, rhythm game pioneer Masaya Matsuura sang this futuristic, outer space rendition of Nat King Cole's "Unforgettable". I imagine every attendee in the room couldn't help but smile with this surprise song, swaying back and forth, arm in arm. According to GameCity organizers, Matsuura's performance "pretty much capture[d] the spirit of the event".

The PaRappa the Rapper creator was at the event to talk about his music game work, the latest of which is WINta, a rhythm action title for the iPhone -- it also seems to employ the same digital voice effect Matsuura used for his "Unforgettable" vocals. I haven't seen any details on its release, but you can watch a short preview of an alpha build that was shown at GameCity below:
