Presented by Aoibhinn Ni Shuilleabhain AN CÓR, a four part series, features the experiences of six choirs as they immerse themselves in the culture, language and history of traditional Irish songs such as "Oró mo bhaidín", "Fill a rún o" and "Príosún Chluain Meala".
In each of the first three shows, two choirs compete against each other. Each choir must rehearse the song, learn and understand the words and get the pronunciation right before the judges select one to go forward to the final. The judges are John Fitzpatrick, Bláthnaid Ní Dhonnchadha and Rónán Ó Snodaigh.
While they're rehearsing, Aoibhinn travels the country to learn the back story of the songs themselves and mentors the choirs as they attempt to impress the judging panel with their final polished version. The three successful choirs from the heats will get to compete in the grand final at The Helix Theatre.
