"After what must've been a few painful minutes of rehearsal, a few robots built by the Interdisciplinary Centre for Computer Music Research have performed what we assume to be their first and last paid gig: a rendition of Happy Birthday to celebrate the 100th of the Science Museum in the UK. What's interesting about these bots -- outside of their horrible ear for music and laughable singing voices is the fact that they've actually been programmed to communicate and teach each other to sing through the process of singing to each other. Videos of both painful acts are after the break, and while we wouldn't call it art, we shouldn't throw stones: we've been in plenty of garage bands that sounded quite a bit worse.[Via robots.net]"^^<http://www.w3.org/2001/XMLSchema#string>
