Watch this video featuring an incredible robotic percussionist in concert on HowStuffWorks. Haile is a robotic percussionist that can listen to live players, analyze their music in real-time, and use the product of this analysis to play back in an improvisational manner. It is designed to combine the benefits of computational power and algorithmic music with the richness, visual interactivity, and expression of acoustic playing.
