Q. I saw Coldplay in Birmingham on December 6th and during the concert Chris played a beautiful piece of classical music. It was piece I recognised but do not know the name of.......what was it? I would love to know cheers. Jason

There were actually two classical/instrumental piano pieces played. One was after the stage b set and was an original composition Postcards From Far Away that is on Prospekt's March. As you say you recognised it, chances are that it was the equally beautiful yet haunting piece Chris plays at the end of Politik. It's the sublime Gnossienne No. 1 by Erik Satie.
