In Performance tonight is in two parts and features two outstanding composers who have struck out down new paths of musical exploration.
Part 1: Andrzej Panufnik , composer and conductor, was born in Poland but for the last 25 years he has lived and worked in Britain.
The Symphony of Spheres is his 5th Symphony and he describes it as ' a musical structure influenced by the beauty and mystery of geometry.' This performance, given at last year's Proms, was conducted by the composer.
Antony Hopkins introduces this work, explaining its structure with poker chips, dice and ping pong balls, and the performance itself is illuminated by special visual techniques.
