R&B singer Frank Ocean will headline Lovebox in 2017, his first show in London since 2013.
The elusive musician will play on the Friday night of the two-day festival in Victoria Park next July.
His studio album Blonde, a follow-up to 2012´s Grammy-winning Channel Orange, was one of the most highly anticipated records of 2016 and has not yet been performed live.
The 17-track Apple Music release was accompanied by pop-up stores in London, New York, Los Angeles and Chicago, where fans could obtain hard copies of the album and an accompanying glossy magazine.
It featured Beyonce, Kendrick Lamar and James Blake and came hot on the heels of his 45-minute visual album Endless.
The show is being advertised as a "London exclusive", suggesting Frank may announce more UK shows.
Lovebox takes place on July 14 and 15 2017.
The Saturday night headliner is yet to be announced.
