Celtic Woman is an all-female Irish musical ensemble conceived and created by Sharon Browne and David Downes, a former musical director of the Irish stage show Riverdance. In 2004, he recruited five Irish female musicians who had not previously performed together: vocalists Chloë Agnew, Órla Fallon, Lisa Kelly and Méav Ní Mhaolchatha, and fiddler Máiréad Nesbitt, and shaped them into the first lineup of the group that he named Celtic Woman. Downes chose a repertoire that ranged from traditional Celtic tunes to modern songs.
The group's lineup has changed over the years; in 2009, the group consisted of Chloë Agnew, Lynn Hilary, Lisa Kelly, Alex Sharpe and fiddler Máiréad Nesbitt; Alex Sharpe left the group in May 2010. Eight albums have been released under the name "Celtic Woman": Celtic Woman, Celtic Woman: A Christmas Celebration, Celtic Woman: A New Journey, Celtic Woman: The Greatest Journey, Celtic Woman: Songs from the Heart, Celtic Woman: Lullaby, Celtic Woman: Believe and Celtic Woman: Home for Christmas. The group has undertaken a number of world tours. Cumulatively, albums by Celtic Woman have sold over 6 million records worldwide.
