Driving the news: The DroneArt Show, put on by Fever, is an open-air concert in West Fairmount Park, featuring a fleet of drones that create complex musical arrangements â think animals, ballerinas. On tap are classical scores like Vivaldi's "The Four Seasons" and Tchaikovsky's 'Swan Lake." Worth noting: Tickets ($40-$45) and are going fast. The VIP picnic area has already sold out. What to expect: 500 illuminated drones. 5,000 battery powered candles will surround the audience and musicians.
