This one isn’t that new (made in 2014). I stumbled across it when I was researching drone music. KMel Robotics (supported by the military industrial complex) presents a team of flying robots that have taken up new instruments to play some fresh songs. The hexrotors create music in ways never seen before, like playing a custom single string guitar hooked up to an electric guitar amp. Drums are hit using a deconstructed piano action. And there are bells. Lots of bells.
