Discover the hidden beauty of birdsong with this remarkable new CD from the British Library. Many songbirds, such as the Skylark, Icterine Warbler and Grey Fantail produce songs that astound us with their complexity and speed of delivery. Though these songs never fail to impress, it is almost impossible for the human ear to distinguish the wealth of hidden notes and surprising melodies that make up these remarkable compositions. On this disc original recordings are played alongside digitally mastered versions where the natural speed has been specifically altered to reveal the subtle intricacy of each song in its full splendour. Join us as we enter this unknown world to hear the secret songs of birds.
