Prom 67: Sakari Oramo conducts Sibelius

Prom celebrating Nature in all her moods. A flight of 16 swans was the catalyst for Sibelius’s stirring Fifth Symphony, with its ambiguous, mysterious ending, while for Judith Weir it was nature’s process – forests sprouting outwards from a single seed, endlessly growing and multiplying – that offered inspiration. Nature turns menacing in Mussorgsky’s vivid tone-poem A Night on the Bare Mountain. Boundarybreaking singer Nora Fischer is the soloist in the UK premiere of The Only One by Dutch composer Louis Andriessen, who turned 80 this year.
