What does the underground sound like?
Beneath the earth lies a noisy vibrant place, from the explosive roar of a volcano erupting, the echoes of caverns down to the barely audible grinding of the earth's plates.
All this noise has long inspired composers and musicians - from Stravinsky and Wagner to Howard Shore and Tom Waits, we burrow into the earth itself to uncover the musical treats that lie under our feet. How do you translate the underground into music and does it bear any resemblance to what is actually happening down there?
Tom discovers what really lies beneath with the sound recordist Jez Riley French who reveals the hidden sounds from the earth itself turning to underground woodlice going about their daily business.
Plus music actually made in the deep places of the world - from Pauline Oliveros's Deep Listening Band to the songs of Welsh miners.

What is Sound Art? And why?
Tom Service considers the rise of Sound Art, commonly found in art galleries today, and wonders whether it is a new genre or simply music in an art space? He consults musician and sound artist Mark Fell, finds precedents in Wagner's operas, considers how a 16th-century choral work became a contemporary art installation, and celebrates the American performance artist Laurie Anderson who accidentally had a pop hit with her piece O Superman.
Today, 'amateur' has become a byword for sloppiness and low standards. But for centuries amateurs were the bedrock of musical life and an essential and vitalising force for composers, providing not only a cohort of highly-accomplished performers and the most discerning audience but also a lucrative vein to be mined by music publishers. To find out how and why attitudes changed - and if they are still changing - Tom Service is joined by writer and historian Katy Hamilton.

Why are classical audiences so quiet?
Tom looks at how modern audiences are hooked on silence in the concert hall. Citing a recent incident where the rustling of a sweet wrapper by an audience member in Malmo created a ruckus so powerful that it spilled spectacularly into a violent brawl, Tom will examine why silence is considered so important and noise so abhorrent in classical concerts.
The Power of One
Music where the needs of the one outweigh the needs of the many - but also where the many can become one... Tom Service looks at music performed solo, or in unison. What is happening in music where there is no harmony? And how can a single musical line build a sense of community?
