The Danish String Quartet’s direct, supple and colourful performances fizz with palpable delight in making music. The three Danish members first met as children on a summer camp, became friends then formed a quartet in their mid-teens; their Norwegian cellist joined them in 2008. “Being relatively bearded, we are often compared to the Vikings. However, we are only pillaging the English coastline occasionally,” they declare. The Scandinavian ensemble is, not least, a boon for Danish music, having championed Carl Nielsen’s quartets and beyond. The Nielsen album is a treasure-trove of fantastic music that deserves to be heard far more frequently. And it’s hard to imagine it better played.
