It is always welcome when English music is conducted by those born outside these shores, if only to emphasise its often underappreciated universality. Tadaaki Otaka had chosen as his main work in this RPO concert Walton’s cantata-cum-oratorio, Belshazzar’s Feast, which no less a luminary that Karajan regarded as the greatest choral work of the first half of the 20th century. Influences in the composition of this piece are there many. In his Lancashire childhood Walton would have had the sounds of local brass bands ringing in his ears and heard numerous performances of the great oratorios, including those by Elgar with their model of a continuous music drama. His progression from a chorister in Oxford to the musical enfant terrible of the 1920s was swift. Just before receiving a BBC commission for what eventually turned into a gargantuan choral piece he would have witnessed the stir created by Constant Lambert’s Rio Grande. And the chilling orchestral effects and spookiness just before “the writing on the wall” owe much to the influence of Strauss in Salome. In fact, with two separate brass bands, positioned in this performance antiphonally in the lower boxes, two harps and a battery of percussion including tambourine, glockenspiel, xylophone, gong, anvil, whip and Chinese block, Walton throws everything but the kitchen sink at an expectant audience.
With such a strong narrative element unfolding over ten linked but distinct sections, a lot depends on the ability of the baritone soloist to project the drama and atmosphere of a hedonistic world revelling in excesses of all kinds. Neal Davies communicated much of this decadent spirit very effectively, rising to the cataclysmic “.....was Belshazzar the King slain”, with the final word of this phrase spat out blood-curdlingly, and immediately echoed in similar fashion by the chorus. Earlier, in his unaccompanied recitative, “Babylon was a great city”, his intonation had noticeably wavered.
Otaka took an expansive view of the score, with no great sense of urgency, but alive to the many incidental felicities. This is a piece of wild extremes, with heavy syncopation in the final Alleluias betraying the unmistakeable influence of jazz, and electrically-charged rhythms driving much of the orchestral writing, but it does have a surprising number of chamber-like delicacies and crystalline effects to beguile the ear. Such details were moulded judiciously by Otaka, not least in the many instances where the lower strings – in partnership with the lower brass or contra-bassoon – give expression to the sense of impending doom before Belshazzar meets his fate.
