Opening with Bartok's Music for Strings, Percussion and Celesta, Boulez immediately provided proof of his renowned aural meticulousness, so shaping and weighting the elegantly chromatic, asymmetric lines of the opening fugue that they floated on their way with total freedom while never blurring the exquisitely conceived harmony. It is a work that has fascinated Boulez from his earliest days, predating even his passion for the Second Viennese School, and he never fails to respond anew to its combination of intellectual rigour and dance-like simplicity, revealing much to those who think of him only as an austere and hard-line intellectual.
At the end of the programme, answering Bartok's string sonorities with its apocalyptic use of large wind ensemble was Messiaen's Et exspecto resurrectionem mortuorum. The composer thought of the monumental utterances of its five movements as suitable for vast spaces, even for performances in the open air or on mountain heights. Perhaps there is more of visionary dream here than of practical reality, yet the Royal Albert Hall, which sometimes seems to encompass some huge outdoor space, provides the perfect environment for the work, and on this occasion Boulez's taut control of its static columns of sound allowed them to vibrate with overwhelming splendour.
This provided one of the highlights of the concert, with warmly sonorous playing by the orchestra's wind and brass choirs, but no less impressive was a marvellously poised account of Debussy's Jeux, that breathtakingly intricate masterpiece which, after decades of neglect and devaluation, was resurrected by Boulez and the post-war avant garde as pointing the way to new structural thinking.
Continuously unfolding, ever transforming, evolving, never exactly repeating, Jeux ushers us into an endlessly fascinating world of spirit and feeling. The listener can never seem to pin down its fleeting processes, yet they were miraculously shaped by Boulez and his players, with tempo and texture in a constant state of flux.
Next came a rare opportunity to hear Debussy's magically re-creative orchestrations of his songs, Trois Ballades de Villon and Le Jet d'eau (the normally reliable Phyllis Bryn-Julson a little out of sorts for once), and they were followed by a scintillatingly textured Le Soleil des eaux, music of sensuous appeal and challenging vigour, to which the BBC Singers contributed memorably - altogether an evening to cherish.
