The South Downs is a range of chalk hills that extends for about 260 square miles (670 km²) across the south-eastern coastal counties of England from the Itchen Valley of Hampshire in the west to Beachy Head, near Eastbourne, East Sussex, in the east. It is bounded on its northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs and includes large parts of the Weald.

The South Downs is characterised by rolling chalk downland with close-cropped turf and dry valleys, and is recognised as one of the most important chalk landscapes in England. It is one of the four main areas of chalk downland in southern England.

The South Downs is relatively unpopulated, although in Sussex there has been large-scale urban encroachment onto the chalk downland by major seaside resorts, including most notably Brighton and Hove.

The South Downs has been inhabited since ancient times and at periods the area has supported a large population, particularly during Romano-British times. There is a rich heritage of historical features and archaeological remains, including defensive sites, burial mounds and field boundaries. Within the South Downs Environmentally Sensitive Area there are thirty-seven Sites of Special Scientific Interest, including large areas of chalk grassland.

Richard Gavin Bryars (born 16 January 1943) is an English composer and double bassist. He has been active in, or has produced works in, a variety of styles of music, including jazz, free improvisation, minimalism, historicism, experimental music, avant-garde and neoclassicism.

Born in Goole, East Riding of Yorkshire, England, Bryars initially studied philosophy at Sheffield University before studying music for three years.

The first musical work for which he is remembered was his role as bassist in the trio Joseph Holbrooke, alongside guitarist Derek Bailey and drummer Tony Oxley. The trio began by playing relatively traditional jazz before moving into free improvisation. However, Bryars became dissatisfied with this when he saw a young bassist (later revealed to be Johnny Dyani) play in a manner which seemed to him to be artificial, and he became interested in composition instead.

Bryars's first works as a composer owe much to the New York School of John Cage (with whom he briefly studied), Morton Feldman, Earle Brown and minimalism. One of his earliest pieces, The Sinking of the Titanic (1969), is an indeterminist work which allows the performers to take a number of sound sources related to the sinking of the RMS Titanic and make them into a piece of music. The first recording of this piece appeared on Brian Eno's Obscure Records in 1975. The 1994 recording of this piece was remixed by Aphex Twin as Raising the Titanic (later collected on the 26 Mixes for Cash album).
