Naresh Sohal, born in Punjab in 1939 but resident in the UK for most of his life, was the first person of Indian origin to make his mark as a composer of western classical music, writing works that displayed an unusual fusion of two cultures. The four quartets heard here - two of them being performed for the first time - document Sohal's stylistic journey: the fireworks of Chiaroscuro II reflect the wild energy of European modernism, whereas the three later works are more considered in manner, incorporating occasional echoes of Indian music into their freewheeling counterpoint.
