Although Philip Glass came late to the string quartet, his contribution to the genre has since become a significant one. This disc features the first four of his five quartets, ranging from the uncharacteristic yet fascinating sound-world of the First, through the compact dimensions of the subsequent two (themselves derived from theatre and film scores). The more expansive manner of his Fourth Quartet makes allusions to the formidable string quartet heritage, in particular those of Schubert and Dvořák.
