Coldplay will headline a music concert hosted by charity Sentebale of which Prince Harry is a patron at Kensington Palace on June 28. This was announced by the palace on Wednesday. Tickets for the concert will go on sale at 9 am on Friday.

“We’re delighted to join Prince Harry for this very special concert and to support Sentebale’s incredible work with adolescents affected by HIV in Lesotho and Botswana,” the rock band, said in a statement.

Other performers who will participate include British singer Laura Mvula, the African-Norwegian singing duo Nico and Vinz, and George the Poet.

The concert will be held in the public gardens of Kensington Palace next month. All the funds raised from the event will go to Harry’s charity, which helps children and teenagers living with HIV in sub-Saharan Africa. The proceeds from the concert will go towards the Mamohato Children’s Center in Lesotho opened by Harry in November.

The money will be used for Sentebale’s monthly Saturday clubs, caregiver days and residential week-long camps. Harry established the charity with Prince Seeiso of Lesotho during his gap year in 2006. The two royals launched Sentebale, which means “forget me not” in the local language Sesotho, in memory of their late mothers.

It hosts camps delivering psychosocial support to 1,500 HIV-positive young people each year. Sentebale also expanded its presence from Lesotho to Botswana recently. During the opening of the Center last year, Harry named one of the rooms in memory of his mother, Princess Diana and another after his late nanny Olga Powell, who cared for him and his brother Prince William for 15 years. The royal regularly plays charity polo match the Sentebale Royal Salute Polo Cup, an annual tournament that raises money for his charity.
