Enya (born Eithne Ni Bhraonain) was born into a musical family. Her father, Leo Brennan, was the leader of the Slieve Foy Band, a popular Irish show band; her mother was an amateur musician. Most importantly to Enya's career, was her siblings, who formed Clannad in 1976 with several of their uncles. Enya joined the band as a keyboardist in 1979, and contributed to several of the group's popular television soundtracks. In 1982, she left Clannad, claming that she was uninterested in following the pop direction the group had begun to pursue. Within a few years, she was commissioned, along with producer/arranger Nicky Ryan and lyricist Roma Ryan, to provide the score for a BBC-TV series called The Celts. The soundtrack was released in 1986 as her eponymous solo album.
Enya didn't receive much notice, but Enya and the Ryan's second effort, Watermark became a surprise hit upon its release in 1988. "Orinoco Flow," the first single pulled from the album, became a number one hit in Britain, helping the album eventually sell four million albums worldwide. Enya spent the years following the success of Watermark rather quietly; her most notable appearance was a cameo on Sinead O'Connor's I Do Not Want What I Haven't Got. She finally released Shepherd Moons, her follow-up to Watermark, in 1991. Shepherd Moons was more successful than its predecessor, entering the US charts at number 17 and eventually selling over ten million copies worldwide.
Again, Enya was slow to follow up on the success of Shepherd Moons, spending nearly four years working on her fourth album. The record, entitled Memory of Trees, was released in December of 1995. Memory of Trees entered the US charts at number nine and sold over two million copies within its first year of release. 1997 saw the release of a greatest-hits collection, Paint the Sky with Stars: The Best of Enya, which featured two new songs. Enya's first album of new material in five years, Day Without Rain, was released in late 2000. ~ Stephen Thomas Erlewine & William Ruhlmann, All Music Guide
