The virtuoso violinist Nigel Kennedy became Britain's most celebrated classical musician after the release of his 1989 recording of Vivaldi's Four Seasons, which sold 2 million copies. But Kennedy had alwaysharboured a love of jazz - an affection which the former child prodigy has been pursuing in his new home. Kennedy now lives in Poland, where he fronts an all-Polish jazz band, the Nigel Kennedy Quintet, and has recently founded The Orchestra of Life, an ensemble consisting of mostly young musicians.

In Imagine: Nigel Kennedy's Polish Adventure, Alan Yentob traces Kennedy's personal odyssey, and follows him as he explores the rich musical traditions of his adopted homeland.
