Carl Corcoran and The Blue of the Night recently met Olatz Zugasti, the Basque singer and harpist. She’s part of the acclaimed Benito Lertxundi Band but also has several albums of her own. Introduced to Irish music on hearing the voice of traditional singer Sean Keane, this fascination led to collaborations with Brendan Graham. She visits Carl for a special show, joined for songs and chat by Sean Keane and Brendan Graham.
