In 2015 this legendary Irish duo released its first new studio album in 42 years, 'The Dark Dance', which was launched at the equally legendary music venue, the Half Moon in Putney. The performance mixed Tir na nOg classics with songs from this album. Tir na nOg has been described as alt folk, prog folk, psych folk and even space folk, but the duo, formed by Leo O'Kelly and Sonny Condell in 1970, transcends all these categories.
