Following on from the Contemporary Chamber Works concert of the LSO Futures series, François-Xavier Roth was back less than an hour later with the Symphonic Sound Worlds programme. This formed the second part of his investigation into the nature of the orchestra, its traditional forms and generic makeup. The title “Symphonic Sound Worlds” hints not only at the expansion of orchestral sounds, but also at the effects of these sounds upon the more general “worlds” within which they are deployed. For centuries the symphony could be identified by its formal construction: it was a large-scale orchestral work in which individual movements had particular harmonic and structural functions. However, the augmentation of these parameters brought with it satellite genres and even intrusions upon the symphony itself. The works selected for this second concert – Anton Webern’s Passacaglia (1908), Pierre Boulez’s Notations for orchestra (1978–), the Panufnik Variations (2013) featuring composers associated with the Panufnik Composers Scheme and Claude Debussy’s La mer (1903–05) – bore the vestiges of such a tradition in different ways.
Roth’s decision to commence the concert with Webern’s Passacaglia for orchestra was an imaginative one. The variations revolving around the ghost of a 17th-century bass line are a far cry from the serialist rigour of Webern’s later works. Nonetheless, this was the composer’s first published piece and remains just as successful as his mature contributions. Interestingly, Webern’s fascination with old forms persisted into his later years and informed such works as the Symphony (1928), the Concerto for Nine Instruments (1934) and the String Quartet (1937–38). An aura of historical sound was established across this performance, with the London Symphony Orchestra players relishing swells of dissonance and their eerie recession into the background.
Boulez’s Notations was possibly the highlight of the entire concert. Derived from the Douze Notations for piano (1945), this extraordinary orchestral work has undergone several permutations. Initially, Boulez created a transcribed version for chamber orchestra in 1946, but did not acknowledge this effort as a part of his output. It was only in 1977 that he revisited the material and decided to extend its content. The original piano pieces, minute in their stature, contain deftly chiseled musical profiles indebted to the serialism of Schoenberg and Webern, along with covert glances at Messiaenic harmony. The five orchestral versions performed in this series were rife with instrumental colour, harmonic deviation, extended polyphony and gestural inflection. It was simply staggering that so much fresh material had been drawn from such a crystallized suite. Roth’s leadership was astute, allowing the performers to engage in frenetic dialogues while feeding the rigidity latent in this music. Five separate scores constructed on an almost biblical scale were an effective salute to the aphoristic quality of this music.
