Clannad are an Irish band formed in 1970 in Gweedore, County Donegal. Their music has been variously described as bordering on folk and folk rock, traditional Irish, Celtic and new-age, often incorporating elements of an even broader spectrum of smooth jazz and Gregorian chant. After twelve years of success in the folk music industry, they shot to international recognition in 1982 with the release of the "Theme from Harry's Game", becoming the most successful band in the Celtic music genre. They subsequently went on to bridge the gap between traditional Celtic music and pop music in the 1980s and 1990s with albums such as Macalla and Anam. Their records usually consist of traditional Gaelic ballads, new-age tracks that carry the group's trademark of haunting vocal harmonies, mellow harp-based instrumentals and often upbeat pop-flavoured numbers. During their career they toured the world extensively and gained fans in every major territory. They have recorded in six different languages, most notably in Irish, and their record sales have exceeded the 15 million mark. They are also widely regarded as the band which, for the first time, put Irish traditional music and the Irish language on the world stage and paved the way for many other Irish artists. They have won several notable awards throughout their career, including a Grammy, a BAFTA, an Ivor Novello and a Billboard Music Award.
