Latitude is returning to Henham Park, near Southwold, in Suffolk, this July.
Headliners Wolf Alice, Chemical Brothers, Bastille, Bombay Bicycle Club, Bill Bailey, Katherine Ryan, Jo Brand, Reginald D. Hunter and Simon Amstell top a diverse bill where music meets the arts.
Festival organisers, with the support of sponsor cinch, have refreshed the programme and promise 2021 will be bigger and better than ever, after a difficult year for live music due to Ccovid.
Wolf Alice will headline the main stage for the first time after first performing at the festival in 2013.
Dance favourites The Chemical Brothers will arrive in Suffolk fresh from previous headline sets at the likes of Glastonbury.
