Now, band of drones that can play music

Robot rock-stars! A US start-up claims to have developed a band of drones that can play music better than an average human.
KMel Robotics has posted a YouTube video of its programmed drones playing the "Also sprach Zarathustra," as well as "Carol of the Bells" and "The Star-Spangled Banner."
The company has assembled a band of hexrotor drones 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," the company said.
They even manage to play drums and crash cymbals with the help of a deconstructed piano action, 'The Verge' reported.

The company, founded in 2011 by Alex Kushleyev and Daniel Mellinger, graduates of the University of Pennsylvania, notes that it is supported by Intel and Lockheed Martin in bringing the band together.
The flying musical troupe will be putting on live shows at the USA Science & Engineering Festival on April 26-27 in Washington.
The drones will perform their YouTube hits and more songs.
