The festival will take place near Huntingdon in Cambridgeshire between 24th and 27th July.
Also confirmed as joining the bill are: Hercules and Love Affair, Foreign Beggars, Alabama 3 and John Fullbright. Artists who have previously been announced include Wolf Alice, Little Dragon and Jagwar Ma.
Speaking about Hercules and Love Affair’s appearance, the band’s Andy Butler said: “The Secret Garden Party is legendary. I have had the opportunity to take two versions of the Hercules live show to many festivals, but every now and then get to one where the curation/line up is ace, the location is wonderful, and the overall organization and attitude is stellar – this would be the Secret Garden Party.”
