Deluxe edition includes three bonus tracks. 2015 release. The Enya creative triumvirate - Enya, producer and sound engineer Nicky Ryan, and lyricist Roma Ryan - started work on the album in the spring of 2012. Inspired by Roma's work on a series of poetry books themed around islands and specifically the island of Sark's decision to be designated as a dark sky island, the album's title track was the first song to be written for the collection. The album's buoyantly optimistic first single "Echoes in Rain" possesses an irresistible surge of globe-trotting euphoria which made it an obvious choice as the album's lead track. While it shares the adventurous themes of Enya's breakthrough hit "Orinoco Flow," it's rhythmic march instead celebrates the anticipation of a journey's end.
