Some of the world's top festival acts have collaborated with iconic British department store Selfridges to celebrate the start of the music festival season.
Among them are Empire of the Sun, Florence and the Machine, Paloma Faith - and Marina and the Diamonds who chose a fitting motif to illustrate her song "I Am Not a Robot" - a six foot tall metallic robot called Frank.
The 24 year old says the robot carries a meaningful message.
"Before meeting and discussing it with the designers I kind of sent them a reference of what the song is about which is how emotionally cut off we are now from the world and because of things like success and everyone driving the world to be this perfect place and to be perfect people, it's resulted in society which has more than ever but it's actually quite discontent and empty."
Marina is performing at UK festivals Glastonbury, The Secret Garden Party, Reading and the Isle of Wight this year. Though she's relatively new to the music charts, she's already a music festival veteran, having performed at 28 last summer.
"I actually prefer the vibe of festivals sometimes, especially if you play early evening , everyone's getting really... drunk.. and therefore .. I don't know, there's always a real euphoria in the festival scene and I really think they're the best places to play."
Other shop windows feature a mannequin of Florence from Florence and the Machine reclining with a neon heart and a 'fun felt' display from Hot Chip.
