Tír na nÓg are an Irish folk band formed in Dublin, Ireland, in 1969 by Leo O'Kelly and Sonny Condell. They are often considered as one of the first progressive folk bands with other artists like Nick Drake or group like Pentangle. Their music mainly consists of their own compositions, based on strong Celtic roots and typically featuring intricate acoustic guitar playing and close harmony singing. In their early years, they toured the folk clubs of the United Kingdom or internationally as a support act for several rock bands. Today, they regularly give concerts, especially in Ireland.
