There has been a lot of talk about drones in past weeks. Stories of Amazon using them to deliver packages, and of course we know they are used by the military. But here is a new use: music! KMel Robotics, known for building aerial video/photography solutions has a drone rock band.
You can watch their close to 4 minute video as they play 3 songs: Star Wars Theme, Carol of the Bells, and the National Anthem.
