This week's Backstage Pass podcast is all about the oldest music festival in the world, the Three Choirs Festival. This year marks the 300th anniversary of the event. As the resident orchestra at the festival we were keen to mark this special event by bringing the behind-the-scenes experience of the Three Choirs to your ears. Tune in to hear more from this unique event with interviews from the festival's artistic director, Geraint Bowen, the Philharmonia roadies and our players.
