Coldplay are raising funds for vulnerable children by selling off a graffiti-covered wall which featured on the sleeve of their latest album Mylo Xyloto.

The Viva la Vida hit-makers collaborated with street artist Paris to make the artwork, which will be exhibited at Proud Galleries in London next month in aid of Kids Company, a charity which helps at-risk children in the U.K. capital.

The show will feature three original paintings on canvas by Coldplay and Paris, as well as the original graffiti wall that became the album artwork.

A second wall painted by Paris and children from Kids Company will also be on display alongside signed, limited edition prints of the album artwork and unseen photographs of the band during the Mylo Xyloto world tour.

Frontman Chris Martin says, "Kids Company is a phenomenal organization that is very close to our hearts. While we were making the last album we did quite a lot of painting with our friend Paris.

"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. This exhibition will be the first time that the wall has appeared in public."

Drummer Will Champion adds, "The big wall and the three paintings are all one-off Coldplay/Paris originals. The money raised will make a big difference to some of London's most vulnerable children."

Kids Company founder Camila Batmanghelidjh praised the band, saying, "The support Coldplay have given us over the years has been amazing. Art plays a major role in Kids Company's work with vulnerable children: kids who have experienced trauma often find it easier to express themselves using art materials rather than words."
