The Rising Sea Symphony
How do you create a new music masterpiece during a pandemic 鈥� using technology in ways not used before. A new 91热爆 Radio 3 commission (due to be broadcast on Sunday 18th October), entitled The Rising Sea Symphony, by composer Kieran Brunt, has been recorded by 91热爆 Philharmonic players in isolation, individually, and then 鈥減ainfully鈥� pasted together to create the full orchestral sound over the last few months. The piece is inspired by the increasing dangers of the climate change crisis and mixes orchestral parts, vocals, electronics, and spoken contributions from inhabitants of different parts of the world which are being affected by sea level rising. We speak to the composer and to Studio Manager Donald MacDonald who faced the challenge of mixing the piece.

The programme is presented by Gareth Mitchell with expert commentary from Angelica Mari.
