What do Coldplay spend $640,000 a night on for their shows? Coldplay Fri-15-Jun-12 17:50 Share this COLDPLAY spent an estimated $640,000 (£400,000)-a-night to supply fans with flashing wristbands that lit up in time to the beat of their music at concerts. The electronic bracelets have been worn by revellers around the world on the band's Mylo Xyloto Tour, filling venues with colour during the group's hits, but frontman Chris Martin recently revealed he and his bandmates were reconsidering using the cool gimmick because it was proving too expensive. He said, "Most of the money we're earning on the tour is put into the wristbands. We have to figure out how to keep it going without going broke because it's a crucial part of the concert." Now guitarist Johnny Buckland has put a price on the bracelets, revealing it has cost the group more than half a million dollars a night to fund the initiative, but he hopes they will be able to continue handing out the light devices for free at gigs - because it really turns concerts into amazing experiences. He tells Bauer Radio, "It looks amazing, it just makes everyone have a great time, most of all us - and it just feels so magical." It is not yet known if Coldplay will use the wristbands when they kick off the second leg of their North American tour in Texas next week.WENN.com You May Also Like Why did Gwyneth and Chris split?
