Jon Hopkins has been added to the final line-up for The xx's Night + Day festival, taking place at Hatfield House in Hertfordshire on June 22.

Hopkins released his new album Immunity this week, of which our reviewer Joe Clay said: "You'll be blessed if you hear a better album of electronic music this year."

He joins Koreless, London Grammar and Floating Points as the new additions, joining The xx themselves and the previously announced Solange, Poliça, Kindness, Mount Kimbie, Benji B and Sampha at the event, which follows previous sold-out one-dayers in Lisbon and Berlin.
