In Thin Air, forms a musical companion piece to Robert and Jackie's book The Book of Birds - a book that is a love letter to the splendours and mysteries of birdlife, and a clarion call to halt the loss of birds from land, sea and sky. The music was created within the contemplative green oak roundhouse of Ty Sanctaidd (Sacred House) in the grounds of Ty Trefacwn in South West Wales, and recorded at Castle Sound Studio in Pencaitland, East Lothian. As with our other albums In Thin Airhas been recorded and produced by Andy Bell of Hudson Records. Throughout The Book of Birds there runs a gentle mantra - " Nest, Egg, Beak, Song, Feather, Flight, Migration -- these are the Seven Wonders that together conjure the miracle of Bird ". Intrigued by this concept, the seven musicians have created an intricate new album that has an overarching narrative, capturing the remarkable world of birds from birth to flight.
