Building on the Irish folk craze ushered by Riverdance in the mid-’90s, Celtic Woman's haunting blend of Gaelic storytelling, lush vocal harmonies and cinematic orchestrations has spanned over 20 studio albums. Formed in 2004, they exploded the following year with a massively popular televised special on PBS. Their eponymous debut would arrive shortly after, holding the No. 1 spot on Billboard's World Music Chart for a whopping 68 weeks. Celtic Woman's traditional folk tunes (“Teir Abhaile Riu”) and fresh interpretations of contemporary hits (“You Raise Me Up”) capture the vibrant spirit of Irish music, past and present.
