Both the songs U.F.O. and Princess of China are on the album Mylo Xyloto from which British rock band?
Princess of China "Princess of China" is a duet recorded by British rock band Coldplay and Barbadian singer Rihanna for Coldplay's fifth studio album "Mylo Xyloto". The song was written by band members Guy Berryman, Jonny Buckland, Will Champion, and Chris Martin, along with Brian Eno, and is influenced by the music genres of electronic rock, electropop and R&B. The song was released as the fourth single from "Mylo Xyloto" and was sent to US Mainstream radio on 14 February 2012. It was later released as a digital download on 13 April 2012. A companion EP to the single, featuring an acoustic version of the song, was released on 1 June 2012.
Xyloband Xylobands are wristbands that contain light-emitting diodes and radio frequency receivers. The lights inside the wristband can be controlled by a software program, which sends signals to the wristband, instructing it to light up or blink, for example. The RGB version has a white strap and can emit any colour on the spectrum. The single colour version is available in green, blue, yellow, red, pink and white. The first use of Xylobands on a large scale was on Coldplay's 2012 Mylo Xyloto tour. A Xyloband was given to each member of the audience, and as the concert played, the flashing of the bands was synchronized to the music. The inventor of the wristbands, Jason Regler, stated that he had the idea for the flashing wristbands while at a Coldplay concert, during the song "Fix You".
