It is a project undertaken by St Davids duo Sky Barkers - Dan Messore (guitars) and Jo MacGregor-Messore (vocals/lyrics) - in collaboration with several other musicians, local authors Elizabeth Daniels & Diana Powell, and the Ancient Connections organisation.
The result is a CD album of 10 beautiful songs and tunes (also available online).
South east Ireland and Pembrokeshire have a number of holy wells, spiritual and magical places dating back to early Christian times. Each of the 10 songs on the album is about a particular well - inspired by incredible tales of goddesses and saints, and Sky Barkers' own direct experiences of the wells.
They hope to encourage people to connect more with natural places, something being lost in modern society.
The songs chosen this week all relate to Pembrokeshire wells.
