Hear the marvellous sounds of Europe's last primeval forest, Białoweiza, in an immersive experience rich with all kinds of bird song and animal sounds, including that of the rare European bison. They're recorded by Polish field recordist Izabela Dłużyk. Izabela is unusual as a young woman recordist, in a profession dominated by men - all the more so because has been blind from birth. She developed a special sensitivity to birdsong ever since her family gave her a tape recorder at the age of 12, and she at once turned its microphone towards the sky. She identifies species entirely though her ears, with an extraordinarily detailed depth of field. Hearing the forest through Izabela’s acute ears, we venture into her world as well as that of the wilderness she loves. Recorded on location in Białoweiza, we also hear night and dawn recordings that bring all sorts of surprises to the microphone. Produced by Monica Whitlock. Mixed by Neil Churchill
