Coldplay have donated the wall from their studio on which the band graffitied the original artwork for their 'Mylo Xyloto' album to Proud Galleries in London. It will be put on sale next month, and proceeds will benefit Kids Company, a charity that provides support for vulnerable children.

“We built a special wall in our studio and sprayed it, wrote on it and threw things at it until it eventually became the artwork for 'Mylo Xyloto,'" Chris Martin tells news.com.au of the piece, which is 23' long by 8' high. "This exhibition will be the first time that the wall has appeared in public.”

Other artwork on display at Proud Galleries and up for sale will include three original paintings on canvas by the band and their 'Mylo Xyloto' artwork collaborator, artist Paris, plus a second wall painted by Paris and children from Kids Company. "While we were making the last album we did quite a lot of painting with our friend Paris,” adds Martin.

Coldplay have been raising money for the charity for more than four years. “Kids Company is a phenomenal organisation that is very close to our hearts," Martin concludes.
