Addictive elegance

A string quartet consists of four players, and a clarinet quintet five, though the Danish composer Rune Glerup (b. 1981)’s newly recorded works for both ensembles would have you believe their ranks are vastly undercounted. The recipient of last year’s Nordic Council Music Prize for his violin concerto Om lys og lethed (About Light and Lightness), Glerup writes pieces for chamber and orchestra that are often characterized by their multidimensionality: a sonic idea will persistently recur in altered guises, for a sense that one is feeling around different facets of a physical form. Yet the two works on Perhaps Thus the End – brought to life by the impeccable Quatour Diotima and clarinetist Jonas Frølund – are just as potent a demonstration of expansive interiority as they are of surface area.

In the titular string quartet, whose seven movements are named for lines from Beckett’s late prose work Stirrings Still, long tones and galloping motives are seamlessly shuffled amongst the ensemble, generating such a sonority that the group seems to have doubled in size. The language is sometimes mechanical but never automatic, bending rather into balletic shapes. Glerup is a careful manager of texture, finding grace in unintuitive sounds through skillful layering – to speak merely of how, in a later movement, a harmonic pizzicato punctuates the string equivalent of vocal fry before the group pivots suddenly into stillness.

On the unexpectedly addictive »Still Leaning Towards this Machine«, which is surely among the few times a contemporary clarinet quintet has received that distinction, electronics magnify the ensemble through a subtle stuttering resonance. As a result, across three spunky movements, the group is occasionally transmuted into a sort of paranormal accordion. It’s a wonderfully weird effect that, just as weirdly, the score seems to deliver with a straight face – just one more satisfying surprise among many others on this excellent record.
