A Hopeful Transmission
Mylo Xyloto, released in October 2011.
A Hopeful Transmission was first referenced in the official tracklisting announcement on 9th September 2011. 
In the article by Q Magazine published on 10th October 2011 entitled "First Impressions of... Coldplay's Mylo Xyloto" they wrote: "The third interlude of the album veers from the electronic thrum of Mylo Xyloto and M.X.I.X, instead opting for a lush string coda, underpinned by what sounds like, umm, someone playing the spoons in the background."
