Across seas and mountains, rivers, glaciers and deserts… in the centenary year of the BBC, the Proms brings a celebration of its world-famous Natural History Unit through the years, from Sir David Attenborough's pioneering early adventures to an exciting preview of what promises to be the latest blockbuster series, Frozen Planet II.Featuring breathtaking images, natural sounds, spoken words and - of course - music, this spectacular event will include classic documentary scores from renowned composers such as George Fenton, Murray Gold, Sarah Class and Nitin Sawhney and a collaboration by Hans Zimmer and Camila Cabello. The evening culminates with the world premiere of Earth Symphony, a work arranged by Iain Farrington that draws on scores from Planet Earth II, Blue Planet II and Seven Worlds One Planet.Presented by Chris Packham and Megan McCubbin from the stage of the Royal Albert Hall.
