Chart-topping stars JLS are the latest addition to this year's iTunes Festival.
The quartet, who were among the acts performing at the Diamond Jubilee concert at Buckingham Palace this week, will make their debut at the annual free festival.
They join acts as diverse as Jack White and One Direction on the bill for the month-long event.
JLS - whose hits include Everybody In Love and She Makes Me Wanna - will play the Roundhouse in Camden, north London, on September 6.
The shows will be broadcast online and fans can apply for free tickets at www.itunesfestival.com.
