Daniel Hope’s absence after the interval set alarm bells ringing. Was he ill? Had there been a backstage bust-up? No; at least probably not. The culprit seems to have been the billing for this concert with the Basel Chamber Orchestra, for it seemed to suggest that the British virtuoso would be directing the entire evening whereas in fact he was just a guest soloist in two first-half concertos.
It was an intimate gathering since only the orchestra’s string sections have travelled to the UK. They cleave to the contemporary fashion of standing throughout and playing to the light-touch gestures of their leader (here Anders Kjellberg Nilsson), a style of music-making that can add vibrancy and vitality to a performance or, just as easily, lead to score-bound flaccidity. Their performance of Bartók’s Divertimento for String Orchestra (1939) had a bit of both. The 20 musicians had the measure of the opening Allegro’s spiky tuttis and free-flowing melodic patterns, but when they divided into sections the first violins in particular were guilty of chugging obediently through the notes. It probably didn’t help that Nilsson had his back to them. Their deficiency was all the more odd since their second-violin colleagues delivered panache and sweep, while Mariana Doughty’s stewardship of the violas ensured that they, too, carried the day.
It’s a cracking work though, cast in three contrasting movements that make a richly coloured whole. The central Molto adagio grows from a seed planted in the low strings and blossoms, if that’s the word, into full-blown Hammer horror: a paragraph of grim, entertainingly baleful music that’s possessed more of fun than foreboding. Both here and in the folksy Finale all was well with the playing, for as the Divertimento danced its way to a conclusion the violinists let their hair fly and their limbs rock to the wit and invention of the music. How do you follow that? A hair-raising encore of Bartók’s Romanian Folk Dances was just the thing.
