The Scottish trio, who recently celebrated the 10th anniversary of their debut album Costello Music with a sell-out UK tour, will be headlining the Saturday night bill at the over-18s festival, taking place from August 31 to September 3.
A regularly short-listed finalist at the UK Festival Awards, this year’s event will be held once again at Beal Farm in an Area of Outstanding Natural Beauty overlooking Holy Island.
The three-day camping festival, which promises its strongest line up to date, will also play host to leading DJs, including Norman Jay MBE and Fun Lovin’ Criminals frontman Huey Morgan.
Other acts include UK festival favourites Showhawk Duo, Beans on Toast, The Lancashire Hotpots, Too Many T’s, The Turbans, Nubiyan Twist and Bryde.
The independent Northumberland festival, which prides itself on championing local talent, will also see another strong line up of North East acts, including Smoove & Turrell, Dansi, Talk Like Tigers, Backyard Rhythm Orchestra and Hip Hop Hooray.
BBC Introducing will also feature at the event, taking over a stage again this year to help put the spotlight on local unsigned talent.
Conleth Maenpaa, founder of Lindisfarne Festival, said: “We are really excited by our line-up and are working hard to secure more great acts, with further announcements to be made in due course, including our Friday headliner.”
Advance tickets for the 3,000 capacity festival are priced at £89 for the three nights, from Thursday to Sunday, £79 for Friday to Sunday, or £55 for Saturday only (with camping included).
