The Book of Days singer has long shunned the idea of hitting the road for an extensive run of shows, because her songs are famous for featuring complex vocal arrangements, but Enya admits modern technology might allow her to layer her voice multiple times live onstage - something that "wouldn't really have been possible" when she first rose to fame in the late 1980s.

"Now it is very, very possible," she tells the BBC. "You see wonderful concerts. There are orchestras there, choirs there, so it's a different time."

Despite this, Enya, who is known for being one of music's recluses, is hesitant to commit to a full tour, adding, "I don't know if that's something I would do."

The 54 year old also claims the decision not to tour earlier on in her career was partly down to record company demands for new music, which would take years to put together.

She continues, "We actually had in my (record) contract that we would have two to three years between each album... So that's why I ended up not touring. The success of (debut album) Watermark caught them by surprise, as it did me. They were worried that if I went on tour and then had three years to work on the next album, it would be too much of a gap."

Enya released Dark Sky Island, her eighth studio album, earlier this month (Oct15). The project features lyrics by poet Roma Ryan and is inspired by the island of Sark, off the coast of France, which locals call Dark Sky Island.

She recently told WENN, "This album has a theme of journeys. Journeys to the island; through the length of a lifetime; through history, through emotions; and journeys across great oceans. So although it's not a themed album, as such, we nevertheless have an underlying connection between songs."

Her last studio album, And Winter Came..., was released in 2008.
