Beth Orton, Neil Hannon and Daughter will also perform at the Irish festival, which has relocated from Dingle to Derry this year after it recently won the title of UK City of Culture 2013.
A special show will also be hosted at London's Barbican Centre in April and streamed online in association BT Infinity.
Other Voices has been billed as Ireland's 'secret festival' since it began ten years ago, with acts including Jarvis Cocker and Richard Hawley playing to a maximum audience of 100.
Amy Winehouse's show at Dingle's church in 2006 was listed by The Times as the 17th best gig of all time.
