Plot: Introduced by Suzy Klein, the Philharmonia Orchestra under principal conductor Esa-Pekka Salonen bring a characteristically colourful programme to the Proms at the Royal Albert Hall, from the scintillating sound world of Ravel's popular Piano Concerto for the Left Hand with soloist Jean-Efflam Bavouzet, to Scriabin's ravishing Poem of Ecstasy and the eagerly-anticipated UK premiere of a new symphony by that giant of contemporary music, Arvo Part.
