Florence + The Machine are playing at an actual Transylvanian castle this July.
This is probably one of the coolest venues I've heard of next to the Egyptian Pyramids where the Red Hot Chili Peppers played last week (check that out here)
Electric Castle is the name of the music festival happening in the historic region of central Romania known as Translyvania on the grounds of a castle.
It's all going down July 17th-21st at Bontida Banffy Castle and the line up is INSANE.
