26 April 2014 Last updated at 00:00 BST
A team of US robotics experts have put together a pop group of flying drones, who will play a string of live dates this weekend.
Daniel Mellinger, a former student of Pennsylvania University and co-founder of KMel Robotics, talked to the BBC about how the band was formed.
The robots will be performing at the USA Science and Engineering Festival in Washington, DC, in a bid to recreate before a live audience what they previously achieved in the recording studio.
