Coldplay has been turning their audience into interactive participants at recent concerts by handing them Xylobands, LED-illuminated wristbands that can be activated all at once using a radio signal. The wristbands come in a variety of colors and have the Twitter hashtag #coldplayfilm printed on them to promote the band’s live DVD. When ‘turned on’ at certain points during the concert, the audience is illuminated with multicolored twinkling lights like a giant display.
The Xylobands help to create a sense of community between the fans and connect them to the artist. After the concerts, they can either recycle the wristbands on-site or keep them free of charge to take home as souvenirs. You can see what they look like in action in the video below:
