The music writer Laura Barton visits four corners of Britain and listens closely to the music found in different landscapes. In this final programme, Laura explores two aspects of musical life in the capital.

Musical migrants, such as the Nigerian-born guitarist Femi Temowo, found a route into London's music scene via the church, whereas the American composer Nico Muhly has been adopted by the city's cosmopolitan contemporary music and arts milieu.

Their experiences contrast with archetypal London musicians Chas 'n' Dave, who made a point of singing in their own accents and created 'rockney' - a hybrid of cockney rock.

Laura examines immigrant and indigenous music within the landscape of London.
