This EP is an interesting addition to Watermark. It samples some tracks from the album itself. And includes a couple of rarities. The highlight of the extra tracks is the inclusion of Silent Night (which would prove so popular that the song would get its own single release in 1991 & turn up on a bonus CD & finally be included on the And Winter Came album).
If you're a Enya completist then this CD is a must. If you're a casual listener then this CD may prove a bit much in the cost needed to have it.
