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.

Our latest podcast is a special extended edition of Backstage Pass, recorded live at Henley Festival. On the 10 July 2015 the Philharmonia Orchestra performed with Gregory Porter, Alison Balsom, Laura Mvula, Shona McGarty, Ballet Black and Ji Liu in a celebration of George Gershwin's music, led by Troy Miller and Fabio D'Andrea. Follow the musicians backstage in this episode for a glimpse of this spectacular event.

The podcast features interviews with Alison Balsom, Gregory Porter, Laura Mvula and dancers from Ballet Black as well as a host of other special guests. 

This week's Backstage Pass is a behind-the-scenes documentary about the orchestra's latest education project. We follow 300 young singers and instrumentalists as they rehearse a work inspired by the discovery of Richard III in a Leicester car park. Composed by John Webb with creative input from the students, the musicians go on to complete a fantastic world premiere performance side by side with members of the Philharmonia.

Share the experience of the group as they find their feet with this ambitious composition, The Last Plantagenet.

Earlier this year the Philharmonia Orchestra recorded tracks for Marvel's Avengers: Age of Ultron soundtrack from Abbey Road Studios, London. For this special edition of Backstage Pass we are happy to feature an extended interview with the film's composer Brian Tyler.
