Folk rockers Mystery Jets have been added to the bill at the Field Day event, billed as a psychedelic summer fete.
The fete takes place on August 11th in Victoria Park in London and features a host of bands and DJs.
Joining the Mystery Jets are 1990s, Alberto Cross, Archie Bronson Outfit, Battles and electro outfit Foals.
Tom Baker, who helped organise the event, said: "Having announced Field Day there seems to be a really positive and exciting buzz about the event.
"We are really happy with the line up and are now working on making the village fete vibe come alive with morris men, a barn dance, bunting, some traditional fair rides, locally-sourced food and much more."
Field Day has a capacity of 5,000 and aims to generate a rather unique atmosphere with the help of some off-the-radar bands.
Also playing at the event will be Electrelane, who have released their new album No Shouts No Calls this week
The kings of psychedelic beauty, the Earlies, will also be playing at the event, as will Pull Tiger Tail, the Aliens, Four Tet and Bat For Lashes.
