A small taster of the sights and sounds of Silver Banks, in the Dominican Republic, from a trip I was lucky to take part in with TBA21, made possible by Francesca von Habsburg. On board the boat was a combination of film-makers, sound recordists and scientists, collaborating on a range of projects, from collecting data on the whales and coral reefs, underwater photography, documentary making and recording the deep blue sounds of humpbacks and coral life for future artworks by Jana Winderen and Chris Watson. Quite a melting pot, and there's more about the TBA21-Academy here. Below is sample of the kind of whalesongs we recorded, some of which continue for 40 minutes or more.
