Hi! I've been driving myself crazy trying to find this video I saw months ago where this female singer was playing the piano on some kind of round platform that was moved by guys while she played. The "platform" moved like one of those "theme park machines", like when you play with a coin and roll it and it starts slowing down until it falls flat. I don't know how else to describe it. I thought she was Lana del Rey or Florence and the Machine, but haven't found anything from them like that video. Help please.
