In the world of classical music Herbert von Karajan's work is so pervasive that it is easy to forget that he is no longer with us. He died 10 years ago, but his music and distinctive theatrical image live on tonight in a special film marking the anniversary of his death, Herbert Von Karajan (World, 9pm). Von Karajan, whose career spanned 60 years, was one of the century's most gifted conductors. His life, was also controversial, bound up with stormy political events in Austria and Germany. He was no Sound Of Music-style hero; while Salzburg's Captain von Trapp stood up against the Nazis, von Karajan performed for them. In 1914, holidaying on the Adriatic coast, the child von Karajan watched the funeral cortege of Archduke Franz Ferdinand, whose assassination sparked World War I, at Sarajevo. Twenty years later he was the darling young conductor of Nazi Germany, and later even conducting the Paris Opera during the Occupation. For that, he harboured a guilt for many years to come. Von Karajan was a man of great paradox. His biographers say he was a jet-setting megastar, yet in reality he was a shy, solitary figure. He was a born teacher and communicated brilliantly with an orchestra but could not communicate on personal matters. He made and sold more best-selling musical recordings than any other conductor - more than 800 - but for him, the Holy Grail remained the live performance. His life and career mirrored aspects of Mozart's; like the great composer, he was born and died in Salzburg and had love-hate links with the musical epicentre of Vienna. The Salzburg Festival, the Vienna Philharmonic and Vienna State Opera, the Berlin Philharmonic, the London Philharmonic and Milan's La Scala were among those to be blessed by his genius. Thanks to his many video and compact-disc recordings, used in tributes like tonight's, his musical legend lives on. Cable viewers can meet a very different extraordinary character in Ralph Bousfield. In a new series starting tonight, Bousfield explores Uncharted Africa (Discovery, 7.30pm). Bousfield has spent his life in the Kalahari desert and in this series, he and his bushman companion Cobra explore this beautiful and dangerous land in Southern Africa, learn how to survive in it and find out about the customs of its people. The adventure begins with Return To Rukwa, in which Bousfield sets out from his animal orphanage in Francistown, Botswana, on a journey to his birthplace in Western Tanzania. Hong Kong has its own wild places as spectacular and beautiful as many more famous wildernesses of the world. Among the most cherished is the Sai Kung East Country Park. Few films, though, get made about our rich natural heritage and this reflects a serious imbalance in local programming and viewing. Luckily, Radio Television Hong Kong is an exception, and it explores Hong Kong's nature in Hong Kong Geographic (Pearl, 6.50pm). The second part of this series, Sai Kung - A Place Of No Wars, visits Sai Kung, contrasting its history as an outpost for resistance fighters during the war against Japan with the natural retreat it is today.
