Former Verve frontman Richard Ashcroft and Supergrass star Gaz Coombes have been added to the line-up of this year's Latitude festival in Suffolk.
The indie favourites will play on the opening night of the 35,000-capacity event at the start of a weekend of music, including headliners Bloc Party, Kraftwerk and Foals.
Ivor Novello Award-winning songwriter Ashcroft will perform at an opening party on the BBC Radio 6 Music Stage on 18 July before the main festival begins the following day.
Coombes will perform his "experimental yet melodious" solo tunes, organisers said.
Latitude, which also includes comedy, theatre, poetry and literature stages, is now in its eighth year.
