Musician Gruff Rhys has been added to the line-up of this year's Dinefwr Literature Festival in Carmarthenshire.
The Super Furry Animals frontman's multi-media tale recounts the story of 18th Century explorer John Evans, a distant relative of his.
The bill also includes singer Charlotte Church and Carmarthenshire singer-songwriter Cate Le Bon.
The festival is a celebration of words, music and landscape from 20-22 June at Dinefwr Park and Castle, Llandeilo.
Church said: "Dinefwr is an amazing, unique event and exactly the sort of special thing that Wales does so well.
"To be surrounded by so many wonderful, creative people in such an incredible setting is going to be a privilege."
Other well known names from the world of music taking part include BBC Radio 1 DJ and writer Huw Stephens, who will present a celebration of the spoken word in music.
The line-up also includes 2013 Costa Award-winning debut novelist Nathan Filer; poet, novelist and children's writer Helen Dunmore; author and journalist Horatio Clare; and National Poet of Wales Gillian Clarke.
The festival started in 2012 and has previously featured writer Howard Marks, musician Julian Cope and poet Sir Andrew Motion.
