From syncopated funk to the Latin requiem mass, Gregorian chant to bureaucratic recitative, the score to David Önaç new oratorio, premiered by the London Symphony Orchestra, is serious and beautiful

How do you put a value on a human life? If you’re an insurance underwriter that’s not a philosophical question, it’s a practical one. The answer, incidentally, as calculated by Lloyds of London in 1779 was £45: the figure placed on each enslaved person transported across the Atlantic alongside corn, fish and other cargo. Court transcripts from two decades later describe a woman quarantined for smallpox, subsequently bound, blindfolded and tossed overboard tied to a chair. The captain later expressed his regret for the loss of “so good a chair”.

Archives can tell us what, but it takes art to give us the human how of the past. Enter composer David Önaç – commissioned to take the historical documents unearthed from the Lloyds archive and give them howling, raging life in his new Atlantic Requiem, premiered this weekend by the London Symphony Orchestra, an expanded BBC Singers, three soloists and (in a last-minute step-in) conductor Malcolm J Merriweather.

Bizet’s incidental music for Daudet’s 1872 play The Girl from Arles was given its first UK complete performance by Sir Mark Elder, the Orchestra of the Age of Enlightenment and strong soloists in Jeremy Sams’ staging

‘The prettiest music in the world” was how the playwright Alphonse Daudet described the incidental music Bizet composed for his 1872 play The Girl from Arles – which is a bit like describing Carmen, the opera Bizet would compose less than three years later, as a charming little love story.

Daudet’s play initially flopped but was saved by the music Bizet wrote for it, which comprises 27 separate numbers ranging from string whispers a few bars long to full-blown orchestral entr’actes and celebratory choruses. Two orchestral Suites from L’Arlésienne have long been familiar in the concert hall. But, after more than 150 years, this was the first chance for UK audiences to hear the complete incidental music in its proper context. Presented by the Orchestra of the Age of Enlightenment and conducted by Mark Elder, there was a danger this play with music could turn into music with a play – but in fact the two elements complemented each other at equal strength.
