Symbiosis (1996)

[...] The quartet lived and breathed together as you would expect, but the piece that followed, Erkki-Sven Tüür’s Symbiosis, a duet for double-bass and violin demanded an entirely different relationship between its two performers, Sian Hicks and Sophie Appleton. The title suggested that the two parts were feeding off each other, each needing the other to survive, but still remaining as two independent organisms, and the music backed up the imagery as the parts shifted in and out of phase with each other. After a languid start, the piece picked up energy, with Sian Hicks at one point sounding like a bass guitarist in a rock band under Sophie Appleton’s wildly vigorous fiddle line.
